Dishwasher not draining or leaking? Same-day service is available — call and describe the symptom.
Call (351) 345-9500When Your Dishwasher Needs Professional Diagnosis
A dishwasher that won’t drain, is leaking onto the kitchen floor, leaves dishes dirty or wet, or has stopped mid-cycle needs professional diagnosis rather than repeated cycle restarts. Running a dishwasher through failed cycles while troubleshooting blind can turn a minor part failure — a clogged filter, a stuck check valve — into water damage on the kitchen floor or cabinetry below.
Book a diagnostic visit if you notice:
- Standing water in the tub after a cycle finishes
- Water leaking from underneath the door or the base of the unit
- Dishes coming out dirty, gritty, or with a film even after a full cycle
- A cycle that stops partway through or won’t start at all
- A persistent bad odor even after cleaning the filter and interior
- Unusual grinding, humming, or clicking noises during the cycle
Symptoms
Common Customer-Described Symptoms
Hudson households call about dishwasher problems in a few recurring patterns:
“It’s not draining — there’s water sitting in the bottom”
Hudson homeowner“It’s leaking from under the door”
Hudson homeowner“Dishes come out with grit or a white film”
Hudson homeowner“Dishes are still wet even at the end of the cycle”
Hudson homeowner“It smells bad no matter how much I clean it”
Hudson homeowner“A cycle used to take an hour and now it takes three”
Hudson homeowner“It stops mid-cycle and the display just blinks”
Hudson homeownerEach of these points to a different system inside the dishwasher, and more than one of these can occur at the same time from a single root cause — a clogged filter, for example, can cause poor draining, gritty dishes, and odor all at once.
That overlap is exactly why “my dishwasher isn’t working” isn’t specific enough to quote a repair. A technician needs to know which of these symptoms is actually present, in what combination, before narrowing down whether the problem lives in the drain system, the water fill system, the heating system, or the control electronics.
Symptom → Cause → Confirmation
Symptom → Possible Cause → Diagnostic Confirmation
| Symptom | Possible Causes | How a Technician Confirms It |
|---|---|---|
| Not draining | Clogged drain filter/basket, failed drain pump, kinked or clogged drain hose, jammed check valve, uncut garbage-disposal knockout plug | Inspects filter and hose for blockage, tests drain pump directly, checks the disposal connection if applicable |
| Leaking from door | Worn or misaligned door gasket, cracked tub seam, overfilling from a failed water inlet valve | Inspects gasket seating and tub condition; tests inlet valve for proper shutoff |
| Leaking from base | Failed pump seal, cracked hose fitting, overfill from a stuck float switch | Runs a diagnostic cycle while inspecting under the unit for the source |
| Dishes gritty or filmy | Clogged filter, worn spray arm nozzles, failed water inlet valve reducing fill volume, hard water buildup (less common given Hudson’s soft water) | Inspects filter and spray arms, tests fill volume and inlet valve |
| Dishes not drying | Failed heating element, faulty vent/fan assembly, rinse-aid dispenser malfunction | Tests heating element resistance and vent fan operation |
| Persistent odor | Trapped food debris in the filter or sump, biofilm buildup in the drain path | Inspects filter, sump area, and drain hose interior |
| Stops mid-cycle | Failed door latch/switch, control board fault, overheat protection trip | Tests door latch switch and control board diagnostics |
| Longer cycle times | Sensor recalibration behavior (normal on some models), failed water heating, sensor fault triggering extra rinse cycles | Tests water heating and turbidity/soil sensor function |
Error codes and blinking lights point toward a general system — drainage, water fill, heating — but the specific failed part still needs direct testing to confirm.
A pattern worth flagging separately: a dishwasher that runs fine for most of the cycle but produces a loud grinding or rattling noise specifically during the drain phase. That’s a strong indicator something has gotten into the drain pump — a piece of glass, a bottle cap, a broken utensil tip — rather than the pump itself having failed outright. A technician checks the pump chamber for debris before assuming the pump motor needs replacing.
Before You Book
Safe Checks Before Booking
A few checks are worth trying before scheduling a visit:
Remove and clean the bottom filter/basket — this is the single most common cause of drainage, odor, and gritty-dish complaints, and it’s designed to be removed by hand
Check that the drain hose isn’t kinked behind the unit if it was recently moved
If you have a garbage disposal, confirm the disposal’s knockout plug was actually removed during installation (a common oversight after a new disposal install)
Run the machine empty on a normal cycle and note exactly where in the cycle the problem occurs
Safety Limits
Clear Stop-Points: When Not to DIY
Dishwashers run on a standard household circuit, not the higher-voltage systems that require the most caution, but a few things are still worth flagging:
Don’t attempt to access or repair the water inlet valve or internal wiring behind the lower access panel — this involves both electrical connections and a pressurized water line.
Don’t keep restarting a cycle repeatedly on a unit that isn’t draining — that can push water higher in the tub and increase the risk of it finding its way past the door seal.
If water is actively leaking onto the floor, shut off the water supply valve to the dishwasher (typically under the sink) and stop running it until it’s inspected.
None of these rise to the level of a gas-line or high-voltage stop-point, but they’re still reasons to have a technician look at it rather than continuing to run a malfunctioning cycle.
Our Method
How a Technician Diagnoses a Dishwasher
Symptom intake
What’s happening, at what point in the cycle, and whether it’s new or has been building over time.
Visual and mechanical inspection
Filter, spray arms, door gasket, and drain hose are checked for obvious blockage or wear.
Component testing
The drain pump, water inlet valve, heating element, door latch switch, and control board are each tested directly rather than assumed from the symptom.
Cause confirmation
The specific failed part is identified — for example, distinguishing a failed drain pump from a simply clogged filter, which look identical from the symptom alone.
Repair or replacement recommendation
Given the confirmed cause and the dishwasher’s age, the technician explains the fix and whether replacement makes more sense.
Inside the Machine
Important Systems and Components
Drain pump
Pumps used water out through the drain hose at the end of a wash or rinse phase; a common source of “not draining” complaints.
Water inlet valve
Controls how much water enters the tub for each fill; a stuck or failing valve affects both fill volume and cleaning performance.
Filter and sump area
Traps food debris before it can recirculate or clog the drain path; needs periodic cleaning by the homeowner and is the first thing a technician checks.
Spray arms and nozzles
Distribute water under pressure; clogged or worn nozzles reduce cleaning performance even when everything else works.
Heating element
Heats water for washing and assists with drying on many models.
Door latch switch
A safety switch that must engage before the cycle will run; a common cause of “won’t start” or “stops mid-cycle”.
Control board
Governs cycle sequencing, timing, and sensor input across the whole unit.
Turbidity/soil sensor
Measures how dirty the wash water is and can extend cycle length or add rinse phases; a faulty sensor is a real, if less common, cause of unusually long cycles.
Rinse-aid dispenser
Releases a small amount of rinse aid during the final rinse to help with drying and spotting; a stuck or empty dispenser can look like a drying problem even when the heating element is fine.
Coverage
Configurations We Service
Built-in undercounter dishwashers — the standard configuration in most Hudson kitchens
Drawer-style dishwashers — single or double drawer units, which use similar core systems in a different form factor
Portable/countertop dishwashers — less common, but the same drain pump, inlet valve, and control board principles apply
Technical Notes
Error Codes and Control-Panel Clues
Modern dishwashers often display a code or blinking light pattern tied to drainage faults, water fill faults, or door latch faults. A drainage error code, for instance, could mean anything from a clogged filter (a five-minute fix) to a failed drain pump (a part replacement) — the code narrows the search, it doesn’t identify the exact cause.
Brand and Model Patterns
Serviceability and parts availability vary by brand and model age. Mention your brand and model when booking so parts availability can be confirmed before the visit.
Repair or Replace
Repair vs. Replacement
| Failure | Typically Worth Repairing | Often Worth Replacing |
|---|---|---|
| Drain pump, inlet valve, door latch switch | Yes | — |
| Heating element | Yes, on most units | — |
| Control board on an aging unit | Case-by-case | Often, paired with other issues |
| Persistent leaks from a cracked tub | — | Yes — a cracked tub is generally not a repairable component |
Dishwashers commonly run 10–13 years with normal use. An appliance well past that range, with a major failure like a cracked tub or a control board issue stacked on prior repairs, is where replacement typically makes more financial sense. This is a general pattern, not a guarantee for your specific unit — the diagnosis determines the actual recommendation.
Repair history is worth paying attention to as well. A dishwasher that’s had one isolated drain pump failure in eight years is a different situation than one that’s needed three separate repairs in the past year — the second pattern often signals broader wear across the unit rather than a single bad part, and it’s worth mentioning that history when you book so the technician can factor it into the repair-vs-replace conversation.
Pricing Context
Cost Factors
Dishwasher repair cost depends on the confirmed failure rather than the symptom label. Variables include:
The component involved and the access required
Whether the problem is inside the dishwasher or in a connected drain/disposal path
Diagnostic time for intermittent control or sensor faults
Brand/model-specific parts availability
See the Appliance Repair Cost Guide for general budgeting factors, not a Hudson-specific quote.
Local Context
Hudson-Specific Context
Hudson, Massachusetts
Hudson DPW supplies municipal water, and the local research pack identifies that water as soft at roughly 8 ppm / 0.5 GPG. That is useful context because a generic “hard-water scale causes dishwasher problems” explanation is not the default for Hudson.
Soft water does not identify the cause of poor cleaning, odor, drainage, or leaking. Those symptoms still require inspection of the filter/sump, spray system, drain path, fill system, seals, heater/sensors, and controls as appropriate.
Hudson also includes older housing, mid-century homes, and newer or converted residential spaces. Kitchen layout and drain/supply routing can therefore vary, but those installation details should be checked at the individual property rather than assumed from housing age alone.
The Visit
What Happens During the Service Visit

FAQ
Frequently Asked Questions
Why is my dishwasher not draining?+
Possible causes include a clogged filter or drain hose, a failed drain pump, a jammed check valve, or — after a recent garbage-disposal installation — a knockout plug that was not removed. Cleaning the filter is the first thing to check; if that doesn’t resolve it, the drain pump and hose need direct testing.
Why is my dishwasher leaking?+
Leaks typically come from a worn door gasket, an overfilling water inlet valve, a failed pump seal, or in rarer cases a cracked tub. Where the water appears — under the door versus under the base — helps narrow which of these is responsible, though a technician confirms it with direct inspection. See our Dishwasher Leaking guide for a closer look at pinpointing where a leak is coming from before booking.
Why are dishes still dirty after a cycle?+
Possible causes include a clogged filter or spray arm, inadequate fill from the inlet system, or wash water that is not reaching the expected temperature. Because Hudson’s water is soft rather than hard, mineral scale is a less likely culprit here than drainage or spray-arm issues.
Why does my dishwasher smell bad?+
Trapped food debris in the filter/sump area and buildup in the drain path are common possibilities. Regular filter cleaning prevents most odor complaints; a persistent smell after cleaning points toward the drain path needing inspection.
How long should a dishwasher cycle take?+
It varies by model and selected cycle, but many normal cycles run 1.5 to 3 hours depending on soil level and whether a heated dry phase is included. A cycle that’s noticeably longer than it used to be, or that seems to run indefinitely, can point to a sensor or water-heating issue worth having checked. See our dishwasher cycle time guide for more detail.
Does Hudson’s soft water affect dishwasher performance?+
It can, though not in the way hard water does elsewhere. Soft water generally means less mineral scale buildup on heating elements and glassware over time, which is a plus. It doesn’t prevent drainage failures, worn spray arm nozzles, or mechanical part wear — those happen regardless of water chemistry — so a Hudson dishwasher isn’t maintenance-free just because the water is soft.
Can I run the dishwasher again if it stopped mid-cycle?+
It depends on why it stopped. If a door latch didn’t fully engage, closing the door properly and restarting is reasonable. If it stopped due to a drainage issue with standing water still in the tub, running it again can push water further and increase leak risk — that’s a better moment to stop and have it checked than to keep restarting.
