A Detailed Overview of Geyser Thermostat Problems

There’s no denying that electric water geysers play a crucial role in the everyday lifestyle of humans. But, unfortunately, electric water geyser issues are commonly associated with a fixed set of symptoms. They essentially include troubles with leaks, water temperature, discoloration, odour, and noise. 

When it comes to building any electric water geyser, you must essentially realize that a thermostat is crucial to its flawless performance. This is essentially a component that allows the user to adjust the water temperature.

Typically, users set their thermostat to a particular temperature and leave it for future use. However, few prefer altering the thermostat settings to suit the intensity of the cold weather.

If you don’t necessarily have technical knowledge about water geysers, you must keep a mental note that thermostats are prone to faults and problems. Here’s a detailed breakdown of the most common thermostat problems. This will essentially help you to identify any potential problem in your electric water geyser without calling any geyser repair team.

Water Not Heating Sufficiently


Firstly, the most common issue with a geyser thermostat is inadequate heat in the water. According to geyser service professionals, this issue is related to the malfunctioning of thermostats. Since the thermostat may be set at a lower temperature; thereby, the water is getting a low temperature from the geyser.


It would be best if you readjusted the thermostat to your desired water temperature.

  • Reach the power mains of the house and turn off the supply to the geyser
  • It would be best if you used a small screwdriver to turn the thermostat
  • Ensure that the water is heating as per your need
  • If not, you may set the thermostat to an even higher degree.
  • Stuck Thermostat


Secondly, people also struggle with a stuck thermostat when using electric water geysers. This essentially means the thermostat knob in your water geyser is stuck at a certain point. This can effectively result in either boiling water or bone-chilling cold water- at all times.


There is only much that you can do to improve the situation with your geyser thermostat in this regard. This is when you must call geyser service professionals to repair or replace the thermostat altogether.

  • Thermostat Faults At A Certain Point


There might be times when you see that the thermostat knob is moving and turning as per expectation- however, the setting may have gotten stuck at a certain point.


Much like the previous case, you won’t be able to address the situation on your own. Alas, you may call in a professional geyser repair team to look into the matter. Ideally, you may have to replace the thermostat. This will essentially help you to reclaim control of the water temperature.

Why Is the Geyser Overflow Pipe Dripping?

There’s no denying that every geyser, either mains or low pressure, contains a specific expansion relief method. However, it is essential for you to realise that water boiling necessarily increases its density- this essentially requires more space since the geyser will find more pressure developing internally.

Ignoring this pressure or mismanaging it could result in the electrical water geyser exploding as soon as it reaches the maximum pressure limit. Therefore, you must ideally look into the thermostat to avoid such possibilities. Furthermore, it would be best if you also considered some additional factors, such as incoming pressure.

According to the experts, water dripping is relatively standard. However, you must not consider a normal overflow or stream from the geyser as a part of the process. If that’s the case with your electric water geyser, here’s a list of potential reasons that could be responsible.

  • There might have been a recent increase in pressure inside the geyser because of utility improvements or repairs
  • This could be the reason due to your geyser overheating. It would be best if you essentially looked into your thermostat for any malfunctioning
  • You must realize that the incoming pressure is often lowered with a pressure control valve in most low-pressure systems. This valve is not long-lasting and typically wears down over time. This eventually leads to more pressure penetrating through. Y9ou may ideally call in geyser service teams to help you in this regard
  • You could also look into the temperature valves or cold water expansion for malfunctioning or build-up of dirt in mains pressure systems. You can access the lever in both the valves that will essentially help you to discharge hot water.

Final Thoughts

In conclusion, it only fits to admit that the article has tried to mention the most common faults for electrical geysers. This will hopefully ensure you make a well-informed decision during your plumbing crisis. Alternatively, if you are not confident about doing the job yourself, you could call in professionals. Mannu Bhai is a reliable name in the industry.
