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

valve or pressure reducing valve has been fitted within the

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.

6)No water at all.

Cause: Valve incorrectly fitted.

Debris in the mains.

Mains water supply turned off.
