FLO error hottub

[kingjon]

Hi, I'm a new owner of an old hot tub. The tub is a 2003 Pacific hot tub. It has been running for a couple of months now. Recently, I've been getting a FLO error intermittently (it causes the heater to stop heating). The display constantly flashes FLO and the current temperature. I've removed the filter so it isn't caused by a dirty filter. Any ideas on what else can cause this? The water level is Ok. The tub leaks about 1" per day.

Thanks,

John

Welcome to TFP John!

Might be a flow switch gone bad on you. Perhaps a better answer will pop up, but wanted to say welcome to the forum.

Thanks - I was thinking the same thing because its intermittent. How difficult is it to replace a sensor?

Love the forum btw. Never owned a pool or hot tub and I was up and running in a few days with advise I read here.

I really don't know to be honest, but perhaps a manual will give you some insight if you can get your hands on one.
