Just set up the spa for the season after been in storage over winter and I have a situation whereby my MSPA Reve JB-301 inflatable spa heater will switch to standby and control panel will power off after about 30mins while heating up the water. The temp has got up to 30 deg C, controller powers on and heater and filter comes on for about 30 mins then switches to standby. I have fitted a new filter and the water level is just below the maximum. Has anybody any ideas's why this would happen.
