How to fix overflowing dishwasher? When a dishwasher overflows, the most likely reason is the float switch assembly. The float itself may be stuck, or the electrical switch that controls the flow of water may be faulty. Neither of these issues is difficult to resolve. In this blog, we also have an article about what are the best commercial dishwashers that you might want to see.
Why Dishwasher Overflow
The Float Assembly Is Immobile Or Defective
When water enters the dishwasher, the float assembly rises, signaling the dishwasher’s water valve to turn off the water. The dishwasher may overfill if the float is stuck in the UP position. Examine the float assembly to see if the float is trapped. Additionally, there is a switch attached to the float that may fail, so inspect both. The float switch is positioned on the dishwasher’s inside bottom.
Excessive Soap Produces Excessive Suds
If the spilling water contains an excessive amount of soap suds, the problem is with the detergent. Using too much detergent might result in a buildup of soapy suds that exceeds the capacity of the dishwasher. When a considerable amount of soap is used, the soap suds grow to the point that they spill out of the dishwasher door and onto the floor.
Using a dollar shop dishwashing detergent may also contribute to this problem, as cheap soap produces an excessive amount of suds. Reduce your soap or dishwashing liquid usage or switch to a different dishwashing detergent.
Faulty Dishwasher Door Gasket
If water or soap suds leak beyond the dishwasher door and onto the floor, the dishwasher door’s sealing gasket is most likely worn out and requires replacement. When the dishwasher door is closed, the water is sealed inside by the rubber seal that wraps around the whole internal door.
Water will pour onto the floor if this gasket becomes torn, brittle, or worn out. Clean the gasket and apply a little bit of petroleum jelly to see if that stops the leak. If you discover that the dishwasher door gasket is in poor condition, you should replace it immediately.
How to fix overflowing dishwasher
Locate the float switch by opening the dishwasher door. It should be a cylinder-shaped piece of plastic that is put to one side along the front of the cabinet or at the sprayer head in the machine’s center.
Verify that the float slides easily up and down its shaft. (To access the float, you may need to unscrew and remove a protective cap.) If the float becomes stuck, wipe away any debris or mineral deposits that may be clogging it.
Remove the float from the shaft and use a bottle brush to clean the inside of the float. Scrub the shaft well with a scrub brush.
Replace the float and verify that it moves freely.
Set the dishwasher to fill and monitor it to ensure it does not overflow. If the float switch continues to malfunction, it must be replaced.
Disconnect the dishwasher from the power source by disconnecting it or turning off the circuit breaker.
Remove the service panel that runs along the dishwasher’s bottom front edge. If it is fastened to the dishwasher, use a screwdriver to remove the screws. If the panel is suspended from hooks, take it out and swing it up to free it from the hooks.
Determine the location of the float switch. Wrap each wire with masking tape and identify each one to ensure proper reinstallation on the new switch. Then, using needle-nose pliers, remove the wires.
Remove the old switch by loosening the bolts using a screwdriver or nut driver and socket.
Take the switch to an appliance store and get a replacement that is an exact match.
Replace the switch and connect the wires.
Replacing the service panel, powering on and testing the unit.
