How do I know if my geyser thermostat is bad?

If your geyser thermostat is malfunctioning, it can lead to various issues such as inconsistent water temperature, inadequate heating, or water that’s too hot. Here are some signs that may indicate a faulty geyser thermostat:

  1. Inconsistent Water Temperature: If you notice that the water temperature from your geyser fluctuates significantly, with periods of very hot water followed by cold water, it could be a sign of a malfunctioning thermostat.
  1. Water Not Heating Properly: If the water from your geyser is consistently lukewarm or not heating up to the desired temperature, it may indicate a problem with the thermostat not signaling the heating elements to activate properly.
  1. Water Too Hot or Scalding: Conversely, if the water from your geyser is consistently too hot, even when set to a lower temperature, it could indicate a thermostat issue where it fails to regulate the temperature effectively.
  1. Visible Damage or Corrosion: Inspect the thermostat for any visible signs of damage, such as corrosion on the contacts or wires. Physical damage or corrosion can interfere with the thermostat’s operation.
  1. Thermostat Clicking On and Off Rapidly: If you hear rapid clicking noises coming from the geyser’s control panel, it could indicate that the thermostat is cycling on and off too frequently, which may be a sign of a faulty thermostat.
  1. Thermostat Settings Not Responsive: If you adjust the thermostat settings, but there’s no change in the water temperature produced by the geyser, it could indicate a problem with the thermostat’s responsiveness.
  1. Age of the Geyser: If your geyser is relatively old and has not been serviced or maintained regularly, it’s more likely to experience thermostat issues due to wear and tear over time.

If you suspect that your geyser thermostat is faulty based on these signs, it’s advisable to have it inspected and tested by a qualified technician or plumber. They can diagnose the problem accurately and recommend the necessary repairs or replacements to restore your geyser’s functionality.
