Expert Dishwasher Repair Throughout Marin County
A malfunctioning dishwasher is more than an inconvenience — it disrupts your daily routine and can lead to water damage if a leak goes unaddressed. At A1 Appliance Repair, we have been diagnosing and fixing dishwashers across Marin County since 2012. Our technicians are experienced with every major brand and failure mode, and we bring the parts and tools needed to complete most repairs in a single visit.
Common Dishwasher Problems We Fix
Dishwashers are complex appliances with multiple systems working together — water supply, heating, washing, draining, and drying. When any one of those systems fails, the results range from cloudy glassware to standing water on your kitchen floor. Here are the issues we resolve most often:
Dishes Not Getting Clean
If your dishes come out with food residue, grease, or a cloudy film, the problem is usually clogged spray arms, a dirty or damaged filter, low water temperature, or a failing wash pump motor. Spray arm nozzles can become blocked by hard water deposits or small food particles, reducing water pressure and coverage. We clean or replace spray arms, service the filter, and test the wash pump to restore thorough cleaning on every cycle.
Dishwasher Not Draining
Standing water at the bottom of the tub after a completed cycle is a sign of a drain problem. Common causes include a clogged drain hose, a blocked filter basket, a faulty drain pump, or an issue with the garbage disposal connection. Left unaddressed, poor drainage creates odors and can damage the appliance interior. We locate the obstruction or replace the drain pump to ensure your dishwasher empties completely.
Dishwasher Leaking
Water pooling under or around your dishwasher can originate from a worn door gasket, a cracked door latch assembly, a leaking water inlet valve, a damaged tub, or loose hose connections. Even a small leak can cause significant water damage to cabinetry and flooring over time. Our technicians pinpoint the source of the leak and make lasting repairs so you can run your dishwasher without worry.
Door Latch Not Working
A broken or misaligned door latch prevents the dishwasher from starting because the control system requires the door to be fully latched before beginning a cycle. A worn latch mechanism or a faulty door latch switch is typically the culprit. We replace the latch assembly and verify that the door seal makes proper contact to prevent leaks at the same time.
Dishwasher Won't Start
If your dishwasher does not respond when you press Start, the issue could be as simple as a tripped circuit breaker or as involved as a failed control board, a defective door latch switch, or a blown thermal fuse. We systematically test each component to find the exact failure and restore normal operation.
Error Codes Displayed
Modern dishwashers display error codes when they detect a fault. Bosch E-codes, LG OE or LE errors, Samsung codes, and GE fault codes all point to specific subsystems. Our technicians are trained to interpret these codes accurately and address the underlying problem rather than simply clearing the code and hoping for the best.
Spray Arm Issues
Blocked, cracked, or loose spray arms deliver uneven water distribution, leaving portions of the dish rack inadequately washed. We inspect both the upper and lower spray arms, clear mineral buildup from the nozzles, and replace arms that are cracked or worn.

We repair dishwashers from virtually every manufacturer sold in the United States. Our most commonly serviced brands in Marin County include:

Should You Repair or Replace Your Dishwasher?
As a general rule, if your dishwasher is less than 10 years old and the repair cost is less than half the price of a comparable new unit, repair is almost always the more economical choice. New dishwashers also require professional installation, haul-away fees, and days or weeks of wait time. Most of our repairs restore full function at a fraction of the replacement cost.
When we arrive for your appointment, we will diagnose the problem, explain what we found, and give you a complete, upfront quote. If the repair does not make financial sense for your specific appliance, we will tell you honestly so you can make an informed decision.
