Questions & Answers

For Whirlpool Water Level Switch (Part Number: OEM18036840)

1 Answer

Hello Rick, This can be a clog inside the dishwasher pump and motor assembly preventing the diffuser WP8579251 from rotating properly or the diverter W10155344 has failed.

Rob for Model Number GU1200XTLT1

Water gushes out from the bottom middle of the door. We replaced the water inlet valve and door gasket. The float was cleaned and tested the float switch. Had a service technician come and he cleaned out the filter area and all areas he could reach from the inside. This stopped the leaking temporarily but again when water shuts off and wash cycle begins, water leaks out. We re-checked the filter area and there is nothing clogging. When we press cancel, the water pumps out. What else could be wrong?

Hello Rob. Check for bad spray arms. Also, make sure the dispenser in the door is not leaking and make sure your not using to much soap in the unit.

Just, It does sound like the float switch is faulty and would need to be replaced.

Hello Paul, If sufficient water pressure is to the valve to properly close it, the water valve WP8531669 has failed and will have to be replaced to correct the issue. you should also check the flood switch since this should kick the drain pump on if the water level gets high enough.

Carol, The float itself would just pull straight up out of the inner tub of the dishwasher. To remove the float switch, there is a compartment under the unit that houses the float switch that you would remove. This should just be held in by a couple of screws.

Marlene, You will want to check to make sure that the spray arms are not clogged or cracked which would cause wave action in the tub of the unit. If the unit does not stop filling with water and overflows then you would want to check the float switch. Check the continuity. If the switch checks ok then it may be the spray arms or the water valve allowing water to continue to come into the unit.

Hello Gary. If the only way to stop the water was to turn off the water, you will need to order and replace the water valve on the unit.

Hello Phil, There are a couple of things that I would suspect. The water valve could be sticking, causing a longer fill than designed. The water pressure could be low enough that if someone is washing their hands or otherwise using the water, there isn't enough water pressure to close the valve. There could be an over soap situation. The bubbles will jump the air gap at the bottom of the door and pop before they hit the floor, appearing to be a simple water leak. Let us know if we can answer any more questions for you.

Chas, the most common issue for your complaint, is a clogged fill valve W10648041 debris and sediment from the pipes enter the valve and reduces the water flow into the machine. You do want to check the float assembly, manually raise and lower the flaot, make sure it moves freely, and you can hear the water level switch "click" then replace the fill valve. With a proper operating float and fill valve, the water level in the bottom of the tub, after a fill and three to five minute wash, should be in touch with the bottom of the heater element. Thanks and Good Luck
