Our dishwasher, model # GU1500XTLS1, leaked water all over the kitchen floor. The problem was water continued to flow through the water inlet on the side of the wash chamber. We removed the the pump underneath, Part #8268589/REL, and first cleaned and repaired the seal, thinking the seal might be bad, letting water slip by it, even when the water was supposed to be off during a cycle. Well, the water no longer leaked in, but it also didn't flow in during cycles, either.
So we replaced the pump and bled the lines, but the water still won't flow in during cycles. Yes, we have water to the dishwasher. Could the replacement pump be defective. Any other suggestions? Thanks....

The problem was water continued to flow through the water inlet on the side of the wash chamber.
Not sure why you chose to look at the pump but if the above is correct then I would replace the water inlet valve (Item 7 in Section 6). It probably stuck in the open position. The float and float switch (also in Section 6) should have killed power to the water valve once an overfill occurred. Assuming that it did this then the fill valve has a mechanical problem.

Your current problem may be that the float is stuck in the up (overfill) position.

Here is a manual which should help with the repair.

You have to join the site to download the manual but it is free and this is a very good site for manuals and other info for the appliance repair DIYer.

Denman:
Thanks for the reply. We found we could release the float switch manually, but it wasn't doing it on its own. So I'm ordering a replacement switch. Thanks for your help. I'll advise how it turns out.
