I have a Maytag model#MDBH950, the chopper shaft stripped out and replaced. impeller looks good,but it fills, then starts, but then the pump starts to cavatate and no water comes out of spray arms, water fill height looks ok can't find the problem.got any sugestions.
P.S.When it starts it works for about 3 or 4 seconds then the pump starts to cavatate and no water from arms?
Answer Ken, Presumably you installed the motor seal kit 6-919539 with the metal chopper shafts and installed it properly. The correct water level in that style dishwasher should partially submerge the heater element in the bottom of the tub, after a 3 to 5 minute fill and wash. If less than that, there's not enough water in the system, and the pump will cavitate. If the water level is in range then you'll need to check your detergent and rinse agent for "sudsing" or foaming, Bubbles in the water from the detergent or rinse agent will make the pump cavitate as well.
The water level is coming over the inlet side tub. I have check the float switch for function. It seems to be working ie. meter stops beeping when I lift the float. What am I missing? Could it be an intermitent problem with the float switch? I have semihard water with a lot of scale in my tub. Please help if you can. Thanks
Answer Hi Reel. Remove the lower kick panel to see if the float switch and the float stem itself are miscued. If the switch side cover is unhooked from its catches, it will misaligned the float stem not allowing it to work in correspondence with the water level. Remove the float from the tub and see if the soap/food/scum is built up in the hole and stopping smooth operations. The float is part # W10202535. The float switch is also included. Make sure all switch connections are clean and tight. Thank You.
