Troubleshooting
PROBLEMS AND SOLUTIONS - FOR THE INSTALLER
THE WATER IS COLD
•
Check if the current arrives to the terminals of the thermostat, if not, please,
verify the circuit breakers and the disconnecting switch.
•
Using a small flat-head screwdriver, check the security device on the thermo-
stat. It is comprised of a rearmable system on the control cabinet.
•
Check the heating element.
•
If the appliance is used in an "off peak hours" scheme, have the timer controlled
by the competent service-provider.
THE WATER IS BOILING (steam comes out of the taps),
•
Immediately shut down the electrical supply and slowly open the hot water taps.
•
Check the setting and the correct operation of the thermostat.
•
If the appliance is old, check if there are deposits of scale. Descale the appli-
ance, refer to "Descaling the Appliance", page 25.
INSUFFICIENT FLOW OF THE HOT WATER
•
Make sure that there is no pressure drop in the cold water supply, which, if the
check valve does not close correctly, would let the hot water flow back into the
cold water tube.
•
Check the heating element, if it is present, and the correct operation of the
timer within and outside the "peak hours" scheme.
THE SAFETY GROUP LEAKS VIA THE DRAIN HOLE
•
This flow is normal during heating. Make sure that the drain hole of the valve is
properly connected to a draining pipe.
Never block this drain hole
•
If the there is a continuous flow or a flow outside heating periods, have the
supply pressure verified.
•
If the water is very hard, have the heating element cleaned annually and set the
thermostat to 65°C.
