Common dishwasher repair problems and what they may mean
These are common possibilities, not a diagnosis. Exact causes depend on your appliance model and its condition.
Water remains in the bottom
A clogged filter, blocked drain hose, disposal connection, or drain pump may be involved.
Dishes come out dirty
Blocked spray arms, poor water circulation, detergent issues, or low water temperature can affect cleaning.
Dishwasher leaks onto the floor
Door seals, spray arms, hoses, or overfilling may be responsible.
Dishwasher does not start
Door latches, electrical supply, or control faults may prevent starting.
Dishes are still wet
Rinse aid, drying settings, and heating components can affect drying.
Troubleshooting by symptom: what to check and when to call
If you're searching for a particular problem, start here. The checks below are limited to safe, user-accessible steps; they do not replace an on-site diagnosis.
Dishwasher won't drain
Standing water may be caused by a clogged filter, drain hose, sink disposal connection, or drain pump.
What you can check: Clean the removable filter and check the sink drain; disconnect power before inspecting accessible components.
Dishwasher not cleaning dishes
Blocked spray-arm jets, improper loading, low water temperature, or weak circulation can leave food behind.
What you can check: Remove and clean spray arms only as directed by the manual; avoid overcrowding dishes.
Dishwasher leaking from door
A damaged door seal, excessive suds, or a spray-arm fault can send water out during a cycle.
What you can check: Stop the cycle and wipe up water to prevent floor damage.
Before scheduling a repair
Check the appliance's power supply, settings, and any user-accessible filters or vents according to the manufacturer's instructions. Record the model number, error codes, and when the problem began. Never bypass safety switches or attempt electrical, refrigerant, or gas repairs yourself.
If you smell gas, leave the area and contact the gas utility or emergency services. If an appliance is smoking, sparking, or leaking near electrical connections, stop using it and seek qualified help.
