My dishwasher won’t drain. I replaced the drain pump and checked all of the drain lines with a snake. Check valve in drain hose right at pump outlet is working properly. I can see water in the drain hose right after the pump. The drain hose loops on the side of the dishwasher assume like it’s own trap. I don’t see water downstream of that loop. Mia robot be enough pressure to push it over the loop. Drain hose ties in to sink drain just before trap and is clear. Removed screen and cleaned. Water will gravity drain out of the basin through the pump. I thought I heard the drain pump run at the end of the cycle but could have been the circulation pump. Any suggestions on next steps? Control board?

Also, what is the button sequence to run the diagnostic test?

Hi Dan,

I'm attaching your tech. data sheet below, look on Page 6 where it says: Service Diagnostics with Error Codes

What I do is remove the drain hose from underneath the sink plumbing, then get a bucket to catch the water in, then put the drain hose in the bucket and start the drain cycle and watch how fast the water comes out the drain hose into the bucket. It should be a very strong and fast flow out.

Try that and let us know what happens.

Thanks Jake

Unfortunately I broke a plastic part removing the drain hose from the side of the unit, and I’ll get that replacement part next week. I did observe the drain hose during a drain cycle and didn’t see any water in the hose downstream of the drain hose loop. The drain hose attaches to the sink drain just before the sink trap. So I don’t expect a different result by removing the hose and the sink end. I’ll give it a try next wk and let you know what happens

Ok Dan, Give it a try anyways, you may be surprised.

Ok, back together, ran drain hose in to a bucket, and still won’t drain. Ran rinse cycle and still standing water in the bottom. Then ran drain cycle and didn’t hear drain pump come on. Control board?

 

[Jake]

Ok, you will need to remove the electrical connector from the drain pump and get a multimeter and set it on AC Volts, then put your meter leads in the drain pump electrical connector that you just removed from the drain pump, then start a drain cycle and see if your meter reads 120 volts. If so, and the drain pump is not running, then your drain pump is bad. If you DO NOT get 120 volts, then your control board is bad.

Here's the drain pump for your model:
Drain Pump W10914557


Here's the control board for your model: W11228314

Thank you. I already replaced the drain pump but I’ll check it with a meter. Do you have a link to the control board?

 

[Jake]

Here's the control board for your model: W11228314

I had the meter on the wrong setting and it sounded like a blew a fuse, is there one and where is it located?

 

[DanS]

Pretty sure I shorted it across the pins on the drain pump harness connector

 

[Jake]

Your mean your meter blew a fuse? Or the machine blew a fuse?

Is the dishwasher dead now?

Jake

 

[DanS]

Machine blew a fuse I think, will need to check if it’s dead. Terminals on the board are scorched.

 

[Jake]

Ok Dan, order and replace the control board and that should fix it.

Unit is not dead, had 58V across drain pump harness pins during drain cycle

 

[Jake]

58 Volts is too low, you need 120 volts, so order the control board.
