The heater temperature is too high (OHH)* – M030
One of the water temperature sensors has detected a temperature
of 47.8°C in the heater and the spa has been switched off. When the
water temperature falls below 42.2°C you can reset using any button.
See “Flow-related checks” below.
A reset message may be displayed with other messages.
Certain faults require the power to be switched off and on again.
Flow-related checks
Check whether the water level is low, whether something is block-
ing the inlet flow, whether the valves are shut, whether there are any
air pockets, whether too many jet nozzles are closed, and whether
the pump has been primed. Even when the spa has been switched
off, certain systems can activate certain equipment to monitor the
temperature or activate freeze protection.
