Just posting for future reference for those with the same problem: Pentair ic 40 3 years of seasonal use in the northeast . Last year flow light red despite adequate flow. Replaced flowswitch under warranty. Problem solved. Fast forward 8 months later to this swim season (out of warranty)...

I just had this problem (no automation), replacing the key pad fixed it as suggested by ps0303.

Problem still existed with new control board. They got the keypad and returned to install it. Seems that you were right pool clown. Thanks everyone.

They ended up showing up today with little advanced notice. They only replaced the control board as they didn't have the key pad with them in there truck. Hopefully, it does the trick.

Just an update. They ended up replacing the entire cell.

Ok it happened again this morning. Turned itself on to spa mode about 2 hours after pump started. Customer service not available until Monday. In the mean time should I just shut the gasline off so it doesn't ignite? Unfortunately the breaker switch also powers the pump so that is not an option.

We had some nasty thunderstorms roll through prior to this. Never lost power though. All other electronics in the house seem fine.

I have a pentair mastertemp 400 for about a year now without any problems. However twice in the past week I come home from work to find the heater on in spa mode. I do not have automation. In order to turn on the heater I have to manually push either pool or spa mode on the unit. I do have a...
