The solution has been to run the diagnostic cycle: punch three buttons three times, wait for flashing lights, close door, wait 25 minutes for diagnostics to complete, then try a wash cycle again. One or two diagnostic cycles usually does the trick.

The error code displayed at the beginning of the diagnostic cycle is always F6-E4 = float switch open. But I hear the float switch click when I raise and lower the float valve, and the washer always fills and drains flawlessly, so I doubt the float valve switch is bad.

Nor do I think I have a bad door latch, because the washer will always run a wash or diagnostic cycle when I close the door.

I'm guessing my intermittent spraying problem is caused by an intermittently failing circulation pump, and that I should replace it.

Does that make sense? Is there anything else I should check first? Thanks!

After a few troubleshooting sessions I have realized it does not drain while in operation, the bottom fills up till it overflows.

If I push the drain button it will drain. Completely.

A few times in the past, I had success at cutting the power at the breaker, and then it tended to work perfectly for a handful of times afterwards before it would start acting up again. This last time I tried to cut breaker, however, was unsuccessful, and now it won't get past that first stage (which I always have to hit cancel to drain the water, which luckily still works every time). --Funny but not, I broke the breaker switch flipping it too many times, so I had to replace that today.--

By the way, it opens the soap tab after 5 or 10 minutes, even if it's not running/washing. So, some aspects of the "wash" cycle are working, I guess.

All panel lights are working and displaying on top.

This problem has been happening intermittently for over 2 years. Two years ago, I bought a replacement pump, but the dishwasher started working before it arrived. Off and on, this has continued to happen for a few weeks at a time, and we just run a rinse cycle until it fixes itself.

I ended up replacing the pump, but it didn’t make a difference. Any ideas?

I don’t want to rip the pump out before knowing, but is it possible that the pump gets overheated during a cycle and won’t properly work until it cools? I took the drain line loose thinking that was the original culprit and it clears well on it’s own (I blew in it and had no issues). I ran vinegar/baking soda through it a few times as well to help clear that even more.

I have a Whirlpool WDP540hamz4 with the 4-3 error. I've replaced the pump and motor combo unit (with W11613479 I believe), but I still get the same issue. I've also opened up the front and inspected the wires; several seemed to have burn marks. I replaced the one that had the worst of them, but it still has the same issue.

For reference, what's happening is that the 2 internal water fan blade things are not spinning or adding water (at least no water from the top one), but the dishwasher is still having water added to it, and the drain is working.

Thanks!

i've replaced the circulation pump, water inlet valve and the center spray arm. the piping going up the back of the dishwasher isn't clogged as far as i can tell. the rest of the arms spin, but the centre arm refuses to spin? What else could be an issue?
