Why Ariston S 3.5 COM PL Water Heater water is not hot enough?

  Jason JenningsAug 9, 2025
  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. A reduction in the ambient temperature may also be the reason; try switching to a higher temperature setting. Also, check if the mains stop valve is fully open and that there are no other restrictions in the supply line, as the water pressure may be below 100 kPa. If none of these solve the issue, there may be an electrical malfunction, in that case have the heater unit checked by a qualified electrician or contact your local authorised distributor.

  If your Ariston Water Heater isn't producing hot water despite the hot water faucet being fully open, first, check the circuit breaker and voltage at the wiring block to ensure there's electrical power. Also, the activation flow rate needed to turn on the heating element might not have been reached. To resolve this, clean the filter screen, turn the circuit breaker off, open the hot valve to release pressure from the unit, and then turn the circuit breaker back on.

  If water ceases to flow from your Ariston Water Heater, it might be due to a blockage of the spray head or a twisted/blocked flexible shower hose. Try cleaning or replacing the spray head and check the hose for free passage of water, replacing it if necessary. Also, ensure there is a water supply by checking the stop valve is open and there are no blockages.

Why does my Ariston S 3.5 COM PL keep switching off during use?
- R
  Robert JohnsonAug 29, 2025
  If your Ariston Water Heater switches off during use, the issue might be an interruption of the mains electrical supply. Check the incoming power supply, MCB, switches, and supply cabling. Alternatively, the ELSD might have tripped due to possible earth leakage. In this case, check for earth leakage and reset the ELSD. If the problem persists, it's recommended to contact your local authorized distributor for assistance.

  If your Ariston Water Heater's water is too hot, it could be because not enough water is flowing through the heater. Try increasing the flow rate via the outlet tap. Alternatively, an increase in the ambient temperature may be the cause, so consider switching to a lower temperature setting.
