Top 5 Common Potterton Boiler Problems

1. Cycling Fan getting automatically on and off Error Codes: E160, E161

The Potterton boiler cycling fan error is a common problem that occurs when the fan in the boiler experiences issues during its cycling process. This error can be caused by various factors, including a faulty sensor, matters within the PCB, an air pressure switch problem, wiring errors, or even an incomplete combustion process.

The consequences of this error can be severe and start with repeated heating cycles failing to switch on and off adequately, leading to high energy bills and low performance in terms of hot water and heating radiators.

What should you do?

The fault might lie within the PCB, wiring, and air pressure switch, so the casing must be removed. It is essential to contact professionals and let them diagnose the underlying cause of this fault as quickly as possible to address it before any further damage is done.

In addition, regular maintenance checks on the boiler system are essential to prevent such problems from becoming exacerbated.

2. Error code E321: No Hot Water Problem

The Potterton boiler no hot water error fault problem can be caused by various issues, such as a faulty thermostat, a malfunctioning diverter valve, or a blocked plate heat exchanger. It won’t display any error codes on the display screen.

One of the most common reasons for this error is a buildup of limescale in the system, which can severely affect the performance of the heat exchanger and prevent it from producing hot water.

Plus, the diverter getting stuck also disrupts the flow of hot water. Please read our article, “A Faulty Diverter Valve,” to learn more.

What should you do?

To fix this issue, you will have to contact a professional, as he will identify the root cause of the problem, which often involves examining the different components of the boiler and carrying out some basic troubleshooting steps.

For instance, cleaning or replacing damaged parts such as thermostats or valves could be necessary. Alternatively, descaling agents can be used to remove any limescale deposits that might be present in the system.

3. Low Boiler Pressure Error Code: E119

The Potterton boiler displaying an E119 fault code indicates low boiler pressure, which can result in a loss of heating and hot water. Low pressure occurs when the system loses water due to leaks or simply because it hasn’t been topped up regularly.

In some cases, the expansion vessel might need servicing, or it could also be that a valve isn’t fully open.

What should you do?

To potentially solve this problem, you should first check if any pipework has been damaged or leaked at any point in the system. If you find leaks in your system, immediately contact a professional.

The professional will inspect the problem in detail and fix the leakage. If you see no leaks, you could repressurise the system using the filling loop.

4. Frozen Condensate Pipe Possible fault code: E133

Potterton boilers suffer from frozen condensate pipe problems, which can cause increased pressure inside the system and lead to a boiler shutdown. This issue occurs when water condenses in the flue and freezes at low temperatures, blocking the pipe that carries wastewater away from the boiler.

What should you do?

To deal with this problem, you can pour hot water on the frozen condensate pipe, which will solve the problem immediately. But this doesn’t mean that it won’t happen again. For a long-term solution, homeowners should ensure that their pipes are insulated and well protected during cold weather conditions.

In addition, regular maintenance checks should be carried out by qualified professionals to ensure that any potential blockages or issues are identified early on.

5. Cold Radiators

Individuals experiencing cold radiators in their Potterton boiler system may be dealing with various potential issues. One possible cause could be an accumulation of airlocks within the central heating system. This can prevent hot water from circulating effectively, leading to cold spots on radiators.

What should you do?

To resolve this issue, you may need to bleed out the radiators and release trapped air through special valves at the top of each unit. Another possible cause could be blocked pipes or radiator valves preventing water flow, which require urgent and prompt repair by a qualified professional plumber to restore heat efficiency and avoid costly bills.
