GQB7420VC159 General Electric Dishwasher - Instructions

Went to repair parts on troubleshooting and found check valve assembly to be most common problem. Went to parts diagram to locate assembly and found it somewhat confusing as to exact location. Ordered part(s) on percentage as the problem. Received part next day (great)! Pulled dishwasher out and found I did NOT need to do so to replace check valve which is replaced without having to remove dishwasher. The gasket replacement was not necessary as it seals sump area from bottom of dishwasher and not the valve as it appears on the parts diagram. It took about 2 minutes to replace valve itself and it was the cause of the problem.

Removed the lower rack. Took off the old wheels. Put the axles on the new wheels which took a little manpower, but became easier once you did a couple (there are 8 wheels). Then snapped the new wheels on the rack which was really simple. The new design is much improved to the old one. The wheels glide better, then they ever did. We're sorry we didn't think of this repair years ago and the cost was a fraction of the cost of a new dishwasher.

Pop the end caps off the slides by pushing the lock tab in with a medium flat screwdriver, through the square hole in the side of the slide. Pull the rack out and set it on the counter. Pop the axles off, with the rollers, with your fingers. They are just clipped on to the rack wire. Pop the new ones on 4 places, fingers only needed to clip them to the wire. Put the rack back in the dishwasher by aligning the rollers in the metal slides and pushing it in like normal. Pop the rack slide end caps in by just pushing them in. If you're smart you bought new ones, they're cheap insurance. Save any good used parts in your kitchen junk drawer for the next time you treat it rough. Less than 5 minutes to fix. So easy a caveman could do it. One just did!

Looked up possible causes on your website. Website stated that more than 50% of time the cause was the piston and nut assembly. Removed the piston and nut assembly in bottom of unit behind screen on rear wall and saw that the gasket seal was completely gone . Ordered the part. took less than 10 minutes to install. Tested the unit and it drained completely. Thank you as i was looking at a more difficult repair if the pump had to be replaced.Repair cost less than $20.00.Before changing piston and nut assembly I cleaned the strainer and sump. disconnected drain hose and checked for blockage . i than checked your website that listed the piston assembly as the culprit more than 50% of the time. Thanks again

Snapped right in

The wheel kit came with axel's to support them. They snapped in place in seconds. No instructions provided, but installing method was obvious.

over time the upper rack axles broke so the rack would just come out of the rollers. I ordered the parts from here and had to youtube how to get the stops out so I didn't have to unscrew the metal guides out making an easy job into a hard one. all you have to do is with a flat head screw driver is slightly bend the plastic end part of the stop which is in the metal guide that stops the wheels from coming out of the guides. once you bend out the plastic end you then turn the stop to get it out of the metal guides. if you youtube it its very easy. just be easy when you bend the plastic piece because I can see it breaking. I didn't break mine so the job was very very easy and took all of about 5 to 10 minutes to complete the entire job. I love this site it had real life info to help out when you need to do a job and trouble shoot your appliance.

Replaced door seal and corner seals. Be sure to heat door seal in dryer be for instillation, 2 minutes. Makes for an easy installation.

The repair was as simple as it could be. The real story is being able to find and replace the missing wheels. Your website makes it real simple to find the proper parts, order them and receive them in a few days. Your parts person; Jason was very nice to send me a little note concerning my order. I appreciate that personal touch. I will be a regular customer with that kind of service. Well done/Good Job.

installed new rollers per diagram then installed side ends into sides. Couldn`t have been easier. Dishwasher is like new now.

My suggestion is to replace all four rollers at the same time since they are all the same age. Fortunately, four rollers come in each pack you order. You need to remove the end cap on borh metal rack rods which takes a little doing. You cannot just pull the caps off. You need to twist the end cap to free up the little catch at the rear of the end cap. Once the end caps are off, just pull of the old rollers and install the new ones, replace the end caps and you're done.

Unscrewed old one and installed the new one.

Removed rack slide end caps. They broke off because of brittleness. Removed rack, then used pliers and/or flat blade screwdriver to remove 4 rollers and axle assemblies. Replaced with new rollers/axles. Return upper rack into slides and installed new end caps. New caps slightly different than old but easily clip into place Upper rack works lile new!

Pulled washer out about 6" without disconnecting any hoses. This way i could use both hands from the left side & front after i took the kick plate off.

Determined not to call a repairman for such a simple problem, I watched your extremely helpful video. The ordered parts came right away and all it took was a screw driver and 30 minutes to take off and replace four rollers. So easy, this 75 year-old grandma could do it!
