Common Dishwasher Issues We Repair
Dishwashers fail in a small handful of predictable ways: dishes that come out dirty, water that will not drain, leaks at the bottom, or a control panel that will not respond. Below are the issues we see most often on Brentwood dishwasher repair calls, and how we resolve them.
Dishwasher Not Cleaning Dishes Well
Dishes come out with food still stuck on, with a film, or with detergent residue that did not rinse away.
Common causes:
- Clogged spray arm jets or worn spray arm bearings
- Failed wash pump or low pump output
- Clogged filter or chopper at the sump
- Inlet water temperature below 120 degrees at the unit
We clean and test the spray arms, clean the filter and sump, verify pump output and inlet temperature, and replace the pump or motor seal if needed.
Dishwasher Not Draining
Water is sitting in the bottom of the tub at the end of the cycle, or the unit pauses mid-cycle with the tub full.
Common causes:
- Clog in the drain pump impeller or chopper
- Failed drain pump motor
- Kinked or clogged drain hose or air gap
- Garbage disposal knockout plug never removed at install
We clear the pump, hose, and air gap, verify the disposal knockout was removed, and replace the drain pump if it has failed.
Dishwasher Leaking Water
Water is pooling under the unit, running across the floor, or visible at the bottom of the door after a cycle.
Common causes:
- Worn or torn door gasket or tub-to-door seal
- Failed pump or motor shaft seal at the sump
- Cracked spray arm or split inlet fill hose
- Failed water inlet valve dripping into the tub
We find the source of the leak, replace the failed gasket, seal, hose, or valve, and verify the unit holds water through a full cycle before we leave.
Dishwasher Not Starting
Pressing start does nothing, the unit beeps and will not run, or the cycle never advances past the initial drain.
Common causes:
- Failed door latch or door switch
- Failed user interface board
- Tripped house breaker or failed power supply at the unit
- Failed thermal fuse on the main control board
We verify power at the unit, test the door latch and switch, inspect the boards for the right voltage at the right pins, and replace the failed component.
Dishwasher Making Loud Noise During Cycle
The unit is grinding, humming loudly, or rattling on every wash or rinse cycle.
Common causes:
- Object stuck in the chopper or pump impeller
- Failed wash pump or drain pump bearing
- Failed circulation motor bearing
- Loose spray arm or worn spray arm bearing
We isolate the source of the noise, clear any foreign object from the pump, replace failed pump or motor assemblies, and verify the unit runs at a normal level.
Error Code or Flashing Lights
A digital display is showing a fault code, or status lights are flashing a service pattern.
Common causes:
- Drain fault from a clogged pump, hose, or air gap
- Heater or thermistor fault during the wash or dry cycle
- Leak detector tripped from a small under-tub drip
- Communication fault between the UI and main control board
We pull the code, cross reference it against the service manual for the exact model, and confirm the reading with sensor tests before quoting parts.
Dishwasher Repair FAQs
Answers to the questions Brentwood homeowners and operators ask us most often, covering common dishwasher failures, service intervals, and how we work.
Why is my dishwasher not cleaning dishes?
The most common causes are clogged spray arm jets, a clogged filter at the sump, a failed wash pump, or inlet water below 120 degrees. Detergent that has absorbed moisture in the dispenser will also leave residue on dishes. We test the spray arms, clean the filter and sump, verify pump output and inlet temperature, and replace the pump if needed.
How long do dishwashers last?
A residential dishwasher typically lasts 9 to 12 years with normal use. Pumps, motors, door latches, control boards, and gaskets are the parts that fail first, usually somewhere between year 6 and year 10. Built-in panel-ready units often outlast standard freestanding units because the cabinet is better protected.
Is a dishwasher worth repairing?
If the failure is a pump, valve, motor, latch, gasket, sensor, or control board, repair is almost always the right call. If the tub has cracked or the unit is over 12 years old with multiple failures stacking up, we will give you an honest repair-versus-replace comparison so you can decide before we order parts.
What dishwasher brands do you service?
We service Bosch, KitchenAid, Whirlpool, GE, Samsung, LG, Miele, Frigidaire, and Maytag, along with most other major brands found in Brentwood kitchens. We carry the most common pumps, valves, latches, and gaskets on the truck so we can complete many repairs on the first visit.
