L1 issue, not staying running

zach_discus · Mar 3, 2019

Hello, bought a complete 250 set up with a L1 as the return pump. Got everything connected and doing my leak test. The L1 will not stay running. Goes for 3-4 min and than shuts off for a few and than restarts. When it shuts of it flashes purple and than turns solid green again when it starts back up.

Any help appreciated.

I think that’s overheat code

Check the impeller, there could be debris causing this issue.

You should probably call them. The early L1's had issues and I have seen almost no help from ETM online in a couple years.

Thanks mfinn, this looks to be a early one. Has a Meanwell driver?!?!

As long as I keep it below 40% it works fine. Just when its turned up is there an issue.
