Storm LGR 1250, how to resolve E4?

Back to List

I bought a Storm LGR 1250 a couple of months ago, used and probably quite out of warranty. It worked well for a few days, then began to fail with E4, which has to do with water level. I went inside, looked at things, and replaced the float switch since that is a recommended fix for this problem. It didn't change anything.

Typical scenario: power up, the initial drain cycle works fine, it runs for 40 minutes or so. Then it gets E4 and nothing but power cycling will make it happy again. But I tested again today, interesting result: it went through several drain cycles running for at least two hours, and then it got stuck with E4. So the pump and the new float switch really, truly work. Something else must be failing.

Is this a well-known issue? Any likely solutions?
