Drain & pump diagnosis
Standing water may relate to the filter, hose, pump or controls. Only clean user-removable parts as instructed by the manual.
Wash performance assessment
Spray-arm movement, loading, detergent, filter condition and circulation can all affect cleaning. Service begins by identifying the pattern of poor results.
Leak detection enquiries
Door sealing, hoses, water valves and internal connections may be inspected. Stop use if water is escaping onto the floor.
Heating & drying enquiries
Cycle choice and loading affect drying. Heater, sensor or control faults may also need assessment, depending on the model.
Inlet & control checks
No filling, interrupted cycles and error codes may involve water supply, sensing or electronics. Do not assume an error means a board replacement.
Maintenance guidance
Use dishwasher-specific detergent and follow the manual for salt, rinse aid and filter cleaning. Hand dishwashing liquid can create excessive foam.
