What to do if Ariston Water Heater has no hot water despite fully open hot water faucet?
- B
  Barbara LynchAug 8, 2025
  If there is no hot water even when the hot water faucet is fully open, first, check the circuit breaker and voltage at the wiring block to ensure there is electrical power. Also, the activation flow rate needed to turn on the heating element might not have been reached. Try cleaning the filter screen, turning the circuit breaker off, opening the hot valve to release pressure from the unit, and then turning the circuit breaker back on.

  The Ariston Water Heater might switch off during use due to an interruption of the mains electrical supply. Check the incoming power supply, MCB, switches, and supply cabling. It could also be due to an ELSD trip, possibly caused by earth leakage. In this case, check for earth leakage and reset the ELSD. If the problem persists, call your local authorized distributor for assistance.

  If the water from your Ariston Water Heater is not hot enough, it could be due to several reasons. First, too much water might be flowing through the heater; try reducing the flow rate via the outlet tap. Second, a reduction in the ambient temperature may be the reason, so switch to a higher temperature setting. Third, the water pressure might be below 100 kPa; check if the mains stop valve is fully open and that there are no other restrictions in the supply line. Finally, an electrical malfunction could be the cause, in this case, have the heater unit checked by a qualified electrician or contact your local authorized distributor.

  Juan EllisSep 2, 2025
  If water ceases to flow from your Ariston Water Heater, it could be due to a blockage of the spray head or a twisted/blocked flexible shower hose. Clean or replace the spray head and check for free passage of water through the hose, replacing it as necessary. Another reason could be no water supply, so check the water supply, ensure the stop valve is open, and verify there are no blockages.
