No hot water when on gas

[Buckman]

Caravan has ALDE heating with ALDE Flow for continuous hot water fitted. Fridge is on gas and no issue with oven and hob. ALDE control panel electric is off and gas selected however no hot water if on gas? Any ideas?

My mistake. I turned off the shower icon instead of the 1, 2-3kw icon. Hot water and heating now default to gas.
