How To Reset A Boiler: A Guide

Having a boiler in your home can be an incredibly convenient way to get access to hot water and heat all year round. However, if you’ve ever had one break down or stop working effectively, it’s likely that you know just how much of an annoyance it can be.

Luckily, there are some simple ways to help prevent any major problems from occurring – like knowing how to reset your boiler before it reaches the point of needing repairs.

In this article, we’ll walk through step-by-step instructions for safely resetting a boiler. However, we do recommend calling in a professional like this London plumber to make sure it is done properly.

Reasons You May Have To Reset Your Boiler

It’s important to watch out for any warning signs that may indicate a problem with your boiler. One of these is if it needs to be reset. Here are some of the most common reasons why you may need to do this:

Overheating

The most common cause of needing to reset your boiler is due to it overheating. If the system has been running for too long, or there is something blocking the heat from escaping, then it can cause excessive temperatures in the boiler and present a risk. In this instance, you will need to switch off the boiler and allow it to cool before starting up again.

Low Pressure Levels

Low pressure levels inside boilers can result in problems that could require resetting – e.g. if there isn’t enough pressure then it won’t be able to generate any heat. So, check on the pressure gauge and refill if necessary in order to get your hot water running again! It’s worth noting that refilling the tank should only be done by an experienced engineer as mistakes could have serious consequences.

Gas Supply Issues

Another potential issue that could require resetting your boiler is a gas supply issue. This would involve checking all wiring/connections between pumps, valves etc. Ensure that they are securely connected as loose connections can lead to failures in other parts of the system and require resetting for safety reasons!

Faulty Thermostat Settings

Your thermostat settings control how much heat is produced by regulating how long the gas supply stays on. If these are incorrectly set then lukewarm water may come out instead of hot water, so inspect them carefully and make sure they’re set correctly! Resetting might also be necessary if any components have become faulty over time or been damaged accidentally.

Electrical Components Needing Replacement

Resetting may also be required when electrical components (such as relays) within the boiler need replacing. This involves contacting an experienced plumber who’ll be able to diagnose the situation and offer more specific advice on how best tackle/resolve any problems.

Checking For Blockages In The Pipes

Steam & hot water pipes can sometimes become clogged with built-up limescale resulting in a lack of hot water supply. If all else fails then you might need to reset the boiler.

Pressure Valves Being Blocked With Debris

Pressure valves play an important role in controlling pressures inside boilers. Therefore, blocked valves with debris can prevent hot water from coming through. So, inspect them first before proceeding further. If anything needs doing then repair/replace accordingly before trying anything else.

How To Reset A Boiler

Resetting your boiler can be a daunting task if you’re not experienced in doing so, however the process is actually quite simple! Before you attempt to reset your boiler, make sure it is safe to do so by following some basic safety steps.

Turn Off the Power

To begin with, switch off the power from the circuit breaker as this will prevent any possible electric shocks. It’s also wise to disconnect all other appliances (such as TVs and computers) that are plugged into the mains before proceeding further. This ensures that no additional current flows through them when resetting takes place.

Check for Obstructions in the System

Check whether there are any obstructions (such as clogged pipes) blocking hot water from coming through. If there are then remove/clear these out of the way so normal flow can be restored again! This might involve calling out an engineer who’ll have specialist equipment on hand which can help here too.

Inspect Flue Pipes & Connections

Next, inspect flue pipes and connections carefully. These may have become loose or disconnected over time which could prevent heat being generated properly and cause faults in other parts of the system. Make sure they’re securely connected and fastened back together before continuing onwards.

Test Pressure Relief Valves

Pressure relief valves play a vital role in controlling pressure levels which in turn affects how much heat is produced by the boiler. Hence, testing, maintenance and replacing old valves every now and again is key to keeping everything running smoothly! If any parts are found to be faulty or worn out then replace/repair/reset according to manufacturer instructions in order to get back up & running again quickly.

Check Ignition Area Components

Ignition area components such as gas valves and pilot lights need to function correctly for any heat generated by the boiler. Test each one individually for proper operation & replace/repair where necessary. This should resolve most problems encountered here.

Ensure Gas Supply Connections Are Secure

Finally, ensure all gas supply connections (e.g. pumps & motors) are securely connected. Loose connections can lead to failures elsewhere & require resetting for safety reasons. So, make sure these components have been inspected thoroughly before completing your resetting process!

Bottom Line

In conclusion, resetting a boiler is an important step in maintenance and should not be overlooked. With the right pre-troubleshooting knowledge, anyone can easily reset a boiler. You should always be aware of any potential problems that may require you to reset your boiler before issues get out of hand.

Should anything go wrong while attempting this task yourself, make sure to call professional help as soon as possible. Plumbers have the proper experience and know-how to handle more complex cases which often arise when dealing with boilers.
