My actual Bosch model # is SHY56A06 UC/23 sn FD8508. It seems like the unit is not getting enough water, the pump is noisy, like it is running dry, but some water does fill the tub, just not enough. I took the supply line off and water is full force. Reading stories here, leads me to the water inlet valve, but it is allowing some water in. Is there a way to "test" or inspect the valve to verify it is the issue, or could it be a water pump after the inlet valve? Is that the circulation pump? Thanks
Answer Hello Tim,
If the unit is not filling with a sufficient amount of water, the water pressure to the unit should be checked first, then the water valve 00425458 should be replaced.
pooling water in bottom I blow through disposal end of discharge hose air does not come out even tried a air compressor! washer stops about 2 min after you start it with water pooling again I clean out the waterwith cup same thing clogged hose,bad pump, pump rebuild kit?? what
You will want to pull the drain hose and check to make sure that the hose is not clogged. Make sure that the flapper that would be on the pump is not damaged. Check for power to the drain pump and make sure that there is power going to it. If no power then the control module would be the issue and if there is power then the drain pump would be the issue providing no clogs in the hose.
I have a Bosch dishwasher and it worked perfectly for 12 years, but yesterday I found a problem: waste water does not go out from the machine in the whole volume. In order to find out reason I disconnected drain hose from the waste line and started the heavy cycle. I have seen rotated part and strong water dropped down as usual, but no one water past through the drain hose from the machine when the cycle was finished. Conclusion: the water comes in but does not pump out. You have part # APZ826384 (Circulation Pump) in your stock but I'm not sure that if I will change it that it will help. Is it reliable to change this expensive part by myself? Thank you
Answer Hello Mark,
If the unit will fill with water and circulate it but will not drain out, the drain pump or a clogged filter is the usual cause. The drain pump can run and be bad. You see, the drain pump impeller is plastic and the drain pump motor shaft is stainless steel. It can separate from the motor shaft and the motor will run and the impel will turn but is incapable of pushing the water out. I have also found in units that have been in place for a long time can have an accumulation of grease in the lower parts of the system to include the drain line. If there are no clogs, the drain pump will solve the issue. The original drain pump has been dis-continued and you have to access the drain pump to determine the correct replacement as follows: If your original drain pump has 9 impeller vanes order 00642239 and 00623143. If your original drain pump has 4 impeller vanes order 00642239 and 00623143.
