Repairing a leaking washing machine can be unreasonably expensive. Frequently, the service technician will charge you a fortune only to visit and diagnose a minor technical issue, a problem which anyone with some technical knowledge may quite easily resolve. The guide offers essential information on diagnosing and resolving the problems you may face when repairing a leaking washing machine.

Step 1 - Identify the Source of the Leak

You first have to first find the source of the leak. These leaks are typically related to the hose, pump, and tub, but be advised that like all machines, your washing machine may have brand-related specifics which may be a source of an uncommon leak.

A word of advice: Always turn off the power supply or unplug your washing machine prior to conducting any repairs on it.

Step 2 - Diagnose Hose Leaks

Leaky supply hoses may be the reason for a leaky washing machine. You may first check if the drain is clogged. If this is the case, simply unclog the drain, and the source of the water puddle on your floor will be removed. If the drain isn’t clogged, move all furniture out of your way and relocate the washing machine into a position, which is comfortable for inspection. Empty the washing machine and start the filling cycle. Pay attention if there are any drips around the supply hose connection. If, while filling it with water, you spot some drips at the back of the machine, then stop the water supply and undertake the necessary steps to remove and replace the old, corroded hoses with new ones. Special no-burst hoses cost twice the regular ones, but they are much better quality. If the hoses look good, you may replace the internal washer. Carefully pull out the old washers by means of a flat-blade screwdriver. After placing the new gaskets in both supply hoses, reconnect the supply lines.

Step 3 - Diagnose Pump Leaks

The washing machine’s pump may be another source of leaks. There are two types of washing machines on the market: a belt-drive washing machine and a direct drive. Open the washing machine's cabinet. If you don’t notice any belt, your machine is a direct drive type. If the pump is leaky, you cannot do much but replace the whole unit. When you open the cabinet to access the pump, you have to relieve the tension on the belt. Loosen the two motor mounting bolts to do that. One of the bolts is always at the rear of the cabinet, the other is nearby. Next, you have to disconnect the pump hoses. Unscrew the pump bolts, tilt the pump pulley away from the washing machine’s belt, and get the pump loose. Direct-drive pumps will have to be simply unscrewed or unclipped. Then install the new pump.

Step 4 - Diagnose Other Reasons for Leaky Washing Machines

Further sources of leaks may be the internal hoses or worn-out tub fittings. If you are unsure of the leak’s source, it may be best to call a professional.
