Cause: Not enough pipe work for expansion; or stop-cock, non-return

distance required for expansion (see page 5, Fig.3). If an

expansion vessel has been fitted, the charge may have failed.

4)No hot water.

Cause: Thermal cut-out has operated.

The heating element has burnt-out.

The thermostat is faulty.

5)Milky water.

Cause: This is a result of heavily limed and oxygenated water being

heated. This is harmless and the cause is the water and not

the heater.

Cause: Valve incorrectly fitted.

Debris in the mains.

Mains water supply turned off.
