10.3 Resetting the safety thermal cutout
DANGER: Electrocution
Do not attempt to reset the safety thermal cutout of
this water heater unless power to the unit has been
completely shut off at the circuit breakers.
26_02_02_1089
The safety thermal cutout on the DHC-E is designed to cut off
electrical power to the heating elements if water of too high a
temperature is encountered. When the safety cutout has tripped,
it must be reset manually.
To reset the safety cutout, use the following procedure:
f Turn off the circuit breaker attached to the water heater
f Remove the front cover of the water heater
f Identify the safety thermal cutout on the top of the copper
heating canister. The button at the top is the reset button.
f Press down on the button, take note of whether it clicks or
not when pressed.
11. Normal maintenance
STIEBEL ELTRON tankless water heaters are designed for a very
long service life. Actual life expectancy will vary with water qual-
ity and use. The appliance itself does not require any regular
maintenance.
However, to ensure consistent water flow, it is recommended to
periodically remove scale and dirt that may build up at the aera-
tor of the faucet(s), the filter screen in the appliance, or in the
shower head.
