Sanicon Water in Back of Motor Housing

So the Sanicon system stopped working on my 2018 377RLBH at the beginning of the summer and I've been troubleshooting it off and on trying to find a simple fix instead of taking it in and not having it for months.

Checked the switch and that was fine, checked the relay and that was working correctly (getting voltage out on the pin when the switch is on).

Finally pulled the motor to make sure it wasn't a short in the system somewhere and when I pulled the back off the housing it was full of water and gunk (it's attached to the black tank so you figure out what I mean by gunk). To note this is in the back half of the housing, not the front half where the impeller is.

When I turn it on with it out of the housing it tries to spin and grinds a bit when it gets about 1/4 rotation then stops again.

Just wanted to double check with those more knowledgeable than and make sure this is not normal. I'm assuming that it lost seal integrity somewhere.

If it is in the back of the motor enclosure it means a housing seal let water in.
If it is in the front by the impeller, then it is usually the impeller seal. Be sure no external water source gets into the motor, you might have to improvise something.

Thank you, looks like I'm going to need a new motor and housing.

I'm guessing the seals probably dried out and cracked in the El Paso heat while I was gone last summer.

automotive silicone will make a good seal. In the housing you always can drill a hole and install a small hose and extend it out of the housing long enough for draining purpose.
But test the motor if it runs properly first.

Ours failed within 6 months of delivery. Started on afternoon when we heard a distinct hum coming from the area by the pantry / fridge. By the time I figured out it was the Sanicon pump, it stopped. The relay was mounted on the basement floor near the 12v pumas and under several water lines, one of which had a intermediate drip that ultimately triggered the relay to activate the pump. The dealer swapped out the relay. Unfortunately, the first time we used attempted to use it, the resettable fuse would trip after about 30 seconds of operation. There’s supposed to be a new pump on the shelf at the dealer waiting to install in a few weeks. I’d like to be able to breakdown the failed pump but no doubt, that would throw a wrench in the warranty process. Fingers crossed.

I noticed that the relay was mounted on the floor directly behind the wetbay with a lot of the water hoses running above it. I just unscrewed it and put in on the wall. Still behind the wetbay so if there is a big water spray there will be an issue but this should at least keep it out of the way of drips. I would recommend to most people to go ahead and change where it is initially mounted. Simply unscrew it from the floor and move it to a way out of the way of water hoses. It is a disaster waiting to happen where it is put at the factory.
