Start by checking for simple issues like ensuring the dishwasher is plugged in and the circuit breaker hasn’t tripped. Clean the filters, check the door latch, and inspect the spray arms for blockages.

Clean the dishwasher filter once a month and wipe down the interior with a damp cloth regularly. Check for debris in the spray arms and around the door seal. Run a cleaning cycle with dishwasher cleaner every few months.

Signs include persistent leaks, strange noises during operation, dishes not coming out clean, the dishwasher not draining properly, or if it fails to start altogether despite being powered on.

It depends on the cause of the leak. Small leaks from loose connections may be fixable by tightening fittings, but larger leaks or those related to internal components like the pump or hoses may require professional attention.

Avoid overloading the dishwasher, scrape excess food off dishes before loading, use dishwasher-safe detergent, and periodically inspect and clean the filter, spray arms, and door seals.

Run the dishwasher only when it’s fully loaded, use the energy-saving or eco mode if available, and choose shorter cycles for lightly soiled dishes. Also, use the air-dry setting instead of heat drying to save energy.
