Do you have a drain pump for this washing machine?

Replaced pump due to a no drain issue #00436440. Evidently this part was superseded by a new # 58300000164288 having a small, manual drain hose attached. In any event, during the fill cycle, the pump is constantly draining. Do you suspect the new pump is faulty?

I have a Bosch washer Nexxt WFCM6400UC. I have just received and installed the replacement drain pump that was provided by your company. it was a bit different than the original, a bit lighter and it contained a manual drain. it was installed from the rear. Although a bit difficult it was easier than taking apart the front cover. Once all the work was complete the water was tuned on and the machine was plugged in. The water fill was filling the machine and the drain was activating at the same time. The machine would start to aggregate at a slow speed.the water would pulse and fill intermittently and when ever the machine took water the pump would drain it out. After about 8 minutes a error code would appear " water tap closed". the tap was open and clear, the filterers were clear, Why would the machine fill and drain simultaneously. Please help it doesn't seem as if it is a siphon problem as indicated on some blog sites.

Latest Questions

When washing sometimes it works fine then the next time it will code E04 which said the unit could be plugged with debris, check it and the pump had some junk but very little. Cleaned the hose from the pump to back of machine. Replaced hose from outside the machine to sewer drain. Put machine in drain or spin and the pump is spinning buy still not draining water all the time. What should I do? Thanks

My tenants have been getting E13 (pump time-out error) intermittently for years, but it seems to be increasing. They could eventually clear the problem and unlock the door by running the drain/spin cycle. I suspected too much detergent was building up, but the problem persisted after they ran 3 cycles with no detergent and 1 cycle with Affresh. Yesterday I disassembled the entire discharge assembly from the sump to the drain hose. There were no clogs. I cleaned everything of soap scum. I tested the pump with 120V ac directly applied to the terminals. The pump ran, but appeared to switch directions (based on the appearance of the vanes occasionally going from a blur to a split-second "frozen image".) In a no-load condition, is the pump supposed to turn in only one direction at constant speed, or is it normal for it to change speed and/or direction of rotation? (Unfortunately, I did not check the resistance across the pump terminals before reassembling it.) Thanks for any help.

I have water in the drain pan under the washer. It appears that the cap for the drain Pump has a bad seal. I can see water coming out of the cap. I took the cap off and cleaned the filter and reassemble the cap. I believe that more water was coming out before the maintenance but there was still water coming out after the maintenance. I had to use a pair of channel locks to get the cap really tight but there is still the table spoon or so that will get past the seal during a complete wash cycle. My question is does Bosch make a replacement seal for the cap or must I by the whole pump assembly which I ASSUME will come with the cap and seal? Can the pump cap with seal be purchased independent of the pump? My pump does not appear to be leaking anywhere else and as near as I can tell there is no other place that the water is coming from. There may be a negligible dribble from the door seal but only a drop or two during the wash cycle nothing that would be a huge cause for concern.
