Already on my third unit in 2.5 years and now it just says "water hot" all the time.
Got a new thermostat on order as it may be that but any other ideas?
4kWp, South facing, 16 x phono solar panels, Solis inverter, Lincolnshire.

    Could be open circuit immersion element. Are you able to check the voltage arriving at the immersion heater? - mine is plugged in to a 13 amp socket, so I can unplug it and connect a lamp or a heater.

    Had my immersion element fail within one month of my immersun being installed. Had it replaced for a much more durable one as my the one in my tank was designed to only be used as a back up if the gas boiler failed. No problems since.

    I also had the water hot message on the unit.

    Glad you've sorted it. I can now joke that with the weather we've had the last couple of days 'course it's going to be HOT! Touch wood I've had mine nigh on 5 years with no problems apart from remembering how hot my hot tap can be!
