What it is

The Ideal 172953 is a domestic hot water (DHW) sensor used across the Ideal Commercial Buccaneer appliance ranges. It measures the temperature of the domestic hot water circuit and passes that reading to the boiler control board, which uses it to regulate burner output and hold a steady hot water temperature at the tap. The sensor is a direct replacement for the factory-fitted item and carries the manufacturer code 172953.

Signs this part needs replacing

  • No hot water at the tap, or water that stays cold despite a DHW demand
  • Hot water temperature swinging between hot and cold during draw-off
  • The appliance fails to fire when hot water is called for
  • DHW-related fault codes or a lockout shown on the control panel
  • A DHW sensor reading that does not match the measured outlet temperature

Before you order

  • Confirm the appliance model and serial number against the compatibility list before ordering.
  • Check the number on the existing sensor; 85754935 and 1179193 both identify this part.
  • Inspect the sensor seal or O-ring at the pocket and renew it if it is perished or damaged.
  • This is not a gas-carrying component, but any work inside the appliance casing should be carried out by a competent person.
