If your dishwasher is making weird noises, leaving dishes dirty, or just won’t start, you don’t have to panic. Most problems are easy to spot and can be solved in under an hour with a few basic tools.
First, always turn off the power and shut off the water supply before you start any work. Safety first keeps you from hurting yourself and prevents further damage to the appliance.
Common Problems and Simple Fixes
Dishwasher won’t fill. Check the water inlet valve for blockages. Remove the filter screen on the valve and clear any debris. If water still won’t flow, test the valve with a multimeter – it should show continuity. A faulty valve usually needs replacement.
Dishwasher won’t drain. A clogged drain pump or block in the hose is the usual culprit. Pull out the bottom rack, locate the pump, and clear any food particles or broken glass. Also, inspect the drain hose for kinks.
Spray arm isn’t rotating. The arm can get clogged with food bits. Remove it (most models just snap off), rinse it under running water, and use a toothpick to clear the spray holes. Re‑attach and run a short cycle to test.
Dishwasher leaves spots on glassware. Hard water deposits often cause this. Clean the filter and run a wash with white vinegar to break down mineral buildup. If spots persist, consider a water softener.
Door won’t lock. The latch may be misaligned or the latch switch could be broken. Inspect the latch for visible damage, tighten any loose screws, and test the switch with a multimeter. Replace the latch assembly if needed.
Regular maintenance keeps problems from returning. Clean the filter after every few cycles, wipe the door gasket, and run a monthly cleaning cycle with a dishwasher cleaner.
When to Call a Professional
Some issues are best left to the experts. If you notice electrical smells, the motor is humming loudly, or the control board shows error codes you can’t decode, call a qualified technician.
Also, if your dishwasher is more than 10‑12 years old and repairs keep adding up, weigh the cost of a new, energy‑efficient model. Modern machines use less water and electricity, which can save you money in the long run.
