Description

Replacement air pressure switch for Camec IWH-1.5 instantaneous gas water heaters. It forms part of the heater's airflow-proving circuit, using the two silicone tubes to monitor exhaust-blower airflow during start-up and operation.

An E9 code indicates a pressure-switch or low-airflow fault, but does not confirm that the switch itself has failed. Before ordering, check for a blocked air inlet or exhaust, moisture, dirt or incorrect connections in the two silicone tubes, low 12V supply voltage, blower faults and loose electrical connections. Replace the switch when diagnosis confirms it is faulty.

Features

  • 1 year warranty.
