I have removed the screw and seal holding the impeller assembly, but the assembly will not come loose. It spins with the motor and when I have applied pressure to lift it off, the assembly cracked a piece off. How do I get the assembly off? My goal is to replace the motor seal as I have leaking below.
Answer TXWIND, On older dishwashers, that can happen on a regular basis. The impeller assembly has a tendency to "stick" to the motor shaft. Due to moisture and debris that accumulates on the shaft.Normally you would have to "break up" the impeller using a screwdriver and hammer, with a soft touch, or cut the impeller off using a "Dremel" tool. Just be careful not to damage the motor tapping or cutting the impeller off.
Water stays at bottom of dishwasher. no circulation with top and bottom arms to cirsulate water.
Answer Bryan, The model number you supplied (JDB-5) is not the model number of your dishwasher. Based on the part number you supplied, you're on track, if the drain hose is not kinked or clogged with debris, and the dishwasher won't wash or drain then the impellers in the pump module could be damaged and not producing the pressure needed to wash, or drain the water from the tub. You will also want to check and make sure the dishwasher is filling up to the proper water level. Start the dishwasher, and allow it to fill and wash for 5 minutes, unlatch, then open the door, remove the lower rack. if the water level is partially to fully covering the heater element then the fill level is correct, and is not the issue for poor washability.
