Troubleshoot a washing machine by checking for common problems such as tripped circuit breakers, clogged drainage hoses and pumps and defective water inlet valves. Start by examining the simplest options such as tripped circuit breakers before proceeding to the more complex issues.
If a washing machine is not operating, first check if it is plugged into a working electrical outlet or reset the circuit breaker. If the washer has overheated, allow it to cool for about half an hour before restarting it again.
If the washing machine does not drain, check if the drain hose or pump is clogged. Clear any obstructions in the drain hose or pump and straighten any kinks. If the problem persists, consider checking if the drive belt is broken or is tight on the pulleys. Tighten a loose drive belt or replace it if broken. If this still does not fix the problem, examine the lid switch assembly and replace it if defective.
If the washer fills slowly, the water pressure from the house may be too low. If the pressure is good, clean the screens inside the water inlet valve. If the problem persists, consider replacing the water inlet valve. For a washer that overflows, first confirm that the air tube to the pressure switch is clear, and then replace the switch if defective.
