Jay,

On the side of the sensor there are pieces that should stick out and the sensor will just push up into place and lock in.

Hello Bill. Check and make sure the water is not flowing back into the unit. If not, then it sounds like the drain pump may be bad A00126401 and need to be replaced on the unit. Make sure the drain hose is not partially blocked on the unit also.

Frank,

With the drain pump running when the unit is not turned on, this would be caused by a faulty control board. The part number that would be needed is 5304514670.

Hello John. Make sure you get the water hot at the sink first. Then if it still does not heat, you will need to replace the control board 807024601 on the unit.

Daw for Model Number FGHD2433KW1 Frigidaire

Unit little used in three years. The water flows to the dishwasher. The drain pump works. The main circulation pump does not work. Have cleaned bottom screen and sump. No debris. Pump impeller turns freely. No error codes on panel. No motor hum. I noted the motor has two power connections and three other wire connections. The two wires are for power to the motor. The other are control inputs/interlocks to the motor? Are there any switches in line with the motor control interlock wiring that can keep the motor from running? What is this switch and how can I test?

1 Answer

Daw,

The switch that you would be referring to would be the hall sensor. The hall sensor can be checked for resistance but the manufacturer does not supply a resistance rating for the part.

Hello Stan. Try replacing the sensor and see if the leak stops. If not, the sump may be bad in the unit.

Allen, Here's some information : " UO > Vent open > While in wash cycle, Main Control Board does not receive signal from vent assembly that vent plunger is closed. Plunger status is sensed with optical sensor in vent assembly. Check wiring between vent assembly and Main Control Board. If wiring correct, replace vent assembly. If error still exist, replace Main Control Board. hs > Hall sensor > The control has sensed an error with hall sensor in motor. Check wiring between motor and Main Control Board. If correct, replace motor. If error still exist, replace Main Control Board. You'll want to recheck the connections at the vent assembly, and check for loose or damaged insulation on the harness at the bottom of the door. Then you'll need to remove the filter screens etc. and check to make sure there are no debris or articles stuck in the impeller on the wash motor assembly.

Ron,

You will want to check the sump to make sure that it is not clogged causing water to not get to the drain pump. Also check for clogged or kinked drain line which would also cause this issue.
