Kenmore 300 Water Softener Troubleshooting
Hi,
Our Kenmore 300 recently failed to stop its recharge cycle. I've powered it down, reset the timer, to no avail. It's throwing Errors ERR01 and ERR04. The valve will either stop in "R" rinse mode or continuously rotate through cycles until I pull the power.
I've checked:
I'm beginning to suspect the timer, since there's nothing else that appears to be wrong.
Thoughts?
THANK YOU!

I've checked:
- Motor works - will turn the valve drive gear as I cycle it using the diagnostic mode on the timer.
- Valve gear and valve - turns OK. I can hear water starting and stopping when I cycle the timer.
- Turbine sensor OK - timer detects water flow, so I know the sensor and wiring are good there.
- Position switch OK - checked with my ohmmeter. Timer faceplate also indicates "--" and "-P" as it opens and closes.
I'm beginning to suspect the timer, since there's nothing else that appears to be wrong.
Thoughts?
THANK YOU!

Some times it is the wire harness from micro switch to control board. It could be a wire or it could be either end of the harness.
There are cheep used ones on E-bay , look for one that looks like yours.

Thank you! I figured it was okay because signal appeared to be going from the timer, but maybe it's intermittent.

UPDATE: The softener worked fine until it called for a recharge and then did the usual thing of sticking in rinse mode in the middle of the night, which probably boosted my water bill for the month. :-/
I decided on an incremental approach and replaced the wiring harness that connects the timer, position switch, and turbine sensor (watersoftenersuperstore.com - reasonable price on new parts and VERY FAST - recommended!). That seems to have done the trick.
It's just weird that the harness would be bad despite it testing OK in place. Ah, well!
