Bosch 00425458 Water Inlet Valve OEM Part

Using instructions I obtained over the internet, I first removed the DW's bottom cover panels so I could look inside the DW (with a flashlight) while it was running. I had to put their dishwasher through several wash cycles before I could pinpoint the location of the leak. (The water appeared to be coming from above on the left side of the DW, near the top, rear of the DW's blue "Pressure Chamber." Thinking that the problem likely lay in either a malfunctioning Pressure Chamber or in a malfunctioning Water Inlet Valve (after I had placed my parts order with APP, an APP tech informed me that the problem most likely involved a malfunctioning water inlet valve, I first decided to replace the valve, because that did not require pulling the DW out from underneath the counter (something I would have had to do to replace the Pressure Chamber). I was aided while replacing the water inlet valve by the video I found on the APP website instructing the end-user on how to replace the valve. The video was especially helpful in determining the proper connections for the wires supplying power to the valve--seeing that the solenoid on the new valve is located 90 degrees counter-clockwise from where it had been positioned on the old valve. After re-connecting everything, the DW experienced a slow water leak from both ends of the elbow-shaped brass connector that connects the Water Inlet Valve to the water supply line. I could not stop the leak with Teflon tape; however, pipe dope applied to the threads of the "male" fittings on the brass connector did the trick and stopped the leak. The DW is now working normally without any water leaks. I will hold onto the Pressure Chamber piece, in case this part malfunctions or breaks at some point in the future.

Replaced water inlet valve.

Web site helped me diagnose problem as water inlet valve not fully shutting off. Repairman quoted me 200.00 to fix, so I decided to gamble the price of the item and repair myself. Web site offered easy to follow, detailed video instructions, had the part replaced and back to working like new in less than 30 minutes.

Dishwasher made a humming sound but no water was circulating around. Searching around, I decided that it was either the inlet valve or the pump/impeller. I started with the inlet valve since it’s an easier repair. It didn’t work, no problem, now I have a spare. I then changed the pump and motor assembly. When I got the old one out, the impeller was broken along with a crack in the plastic housing. The repair took about 3 hours following along with the video. The dishwasher now works like new.

I researched the internet on the symptom, and AppliancePartsPros.com advised the most common problem was the Circulation Pump...seals and broken impeller. It was only by watching AppliancePartsPros.com's repair video, that I was able to accomplish the actual fix. It took about an hour to get to the old circulation pump, and once I had it apart, it was quite obvious the impeller and the bushing seals were toasted. I replaced all the circulation pump parts, replaced the water inlet valve for good measure, and the lower spray arm for as my original was cracked, and the unit is now performing just like it did when we purchased it 10 years ago.
