Your water heater: Troubleshooting guide
Action to take Solution Cause
1. Cut-off the water heater power
(the circuit breaker should be in the
OFF position).
2. Take a resistance measurement at
the heater element terminals using a
multimeter (in ohm position).
Null or innite value. Replace the faulty resistor.
Value in ohms > 0. Replace the thermostat.
V.2 Electric meter which breaks the circuit
Action to take Solution Cause
1. Check that the meter only cuts-
out when the water heater starts
heating.
2. If you have Peak/Off-peak hours
pricing,
2.1 Switch to forced operation
from your electrical distribution
board.
2.2 Check the position of the
circuit breaker (should be
in the ON position).
The meter trips as soon as the
water element circuit breaker
is set to ON.
On a shielded product: Replace
the heater element.
Faulty resistor.
On a steatite product: Clean
the area where the heater element
is located (hollow interior) with
a cloth or a bottle brush.
If the problem persists: Replace
the heater element.
Residue in the resistor sleeve.
Faulty resistor.
V.3 Lukewarm water
Action to take Solution Cause
1.1. Switch off the electrical power
supply to the water heater.
1.2. Open the plastic cover.
1.3. Switch the thermostat to
maximum. See Section III Setting the
temperature.
Leave the thermostat setting at
maximum in order to enjoy very
warm water in sufcient quantity.
Incorrect thermostat setting.
2.1. Shut off cold
water inlet on the
safety unit.
2.2. Turn on a hot water
tap in the house.
If water ows from the hot water
tap, then one of the house’s taps
is faulty.
Replace the faulty tap or consult
a plumber to nd the cause
of the problem.
A tap (mixer) allows cold water into the
hot water circuit.
