SYMPTOM
UNEXPLAINED SHUT-DOWN OF THE APPLIANCE
This appliance contains an Energy Cut-Off Device which reacts when the water in the heat exchanger exceeds the
anticipated temperature limit. Although it is intended to guard against failure of the automatic gas valve, it may be triggered
inadvertently by other causes, especially during the summer months when the inlet water temperature is unusually high.
POSSIBLE CAUSE
SOLUTION
Temperature selector set too high for the time of year.
Select a lower temperature.
However, if the energy cut-off device reacts to a slowly closing automatic gas valve, the shut down of the appliance may be
accompanied by noises from the heat exchanger and pipework. The pressure relief valve located on top of the water
governor may also have vented water into the case. In this situation it is possible that STEAM will come out of the hot water
tap when turned on.
POSSIBLE CAUSE
SOLUTION
Excessive resistance of push rod.
Exchange push rod and seals. Lubricate with Dow Corning Ill
silicone grease and ensure free movement.
IMPORTANT NOTE
To ensure continued safe operation, we recommend that if the pressure relief valve has operated, it
should be replaced immediately
