Evening, I'm after some help with the above water heater. The Malaga 3E is either 240v or gas, on Friday the electric heat element failed, (I've ordered a new one) so I'm using it on gas at the moment which is fine to start with, it ignites, lights and heats the water, the problem comes when the water temperature drops either of its own doing or when I draw water from the taps, this is where the problem starts, it doesn't reignite. If I turn it off and back on it fires up first time, heats the water. Why is it not igniting automatically?
