Customer Question

stayrite heater is throwing code E01 what is wrong

Welcome, how can I help you today? Code E01 is a open thermistor. This link will give you a copy of the parts breakdown.

Open Regulating Thermistor. Error message
shows as soon as error is detected (which can happen
only if the heater is in the POOL ON or SPA ON
mode). The heater will not heat, but all other functions
remain usable. Look on the side of the header of the heater there are two switches on the side one above the other, the thermistor is the top one. Use the link above and look at part #9, replace this switch.
