What does the ER14 fault code mean on my Biasi boiler
If you’ve noticed the ER14 fault code being displayed on your Biasi boiler, there’s a problem with the pump. It’s likely that after the fault code was displayed on the control panel, the boiler locked out.
When a boiler locks out, it’s important to avoid resetting it until the problem has been found and fixed. There’s a good chance that if the boiler continued to operate, further problems could develop with the pump, not to mention other components in your Biasi boiler.
Can the ER14 fault code be fixed on a DIY basis
The inspect the pump, the boiler’s casing is going to need to be removed. That’s classed as working on a gas appliance. And, the only people that are legally allowed to work on these appliances, are trained professionals with Gas Safe accreditation.
So, it’s worth calling an emergency boiler repair company as soon as possible. Once they’ve found and fixed the problem with your Biasi boiler, a reset will help to clear the fault code from the display panel.
How will my boiler repair company know exactly what is wrong with my appliance
Unlike other fault codes that are generic, the ER14 is specific. That’s going to make the fault finding process much quicker for your engineer, and therefore, much cheaper.
But they’ll still need to determine exactly what is wrong with the pump. They’ll be looking out for things like:
- Current speed setting
- Airlocks
- Blockages
- Movement of the shaft
- Quality of the pump’s installation
- Leaks
- Power and communication with the PCB
How could the current speed setting lead to the ER14 fault code being displayed
Most pumps aren’t designed specifically for one boiler, or one property type. To ensure they function in a range of properties and boilers, the best ones have multiple speed settings; three on most occasions.
If the pump is on the incorrect speed setting for your property, you’ll end up with a circulation issue. In most cases, we find a new installation has a pump setting that’s too slow. This means water has plenty of time to lose temperature as it travels around the heating system, meaning the boiler must work overtime to heat it back up.
Your boiler engineer will be able to check the current speed setting of the pump, and then adjust it accordingly. In this instance, it’s unlikely you’ll need to replace the pump, assuming a pump with a reasonable capacity has been installed.
Why do airlocks occur, and can they be removed
When a heating system is topped up, it then needs to be bled of air. Air enters the system with water and this acts much like a blockage. In some cases, the air gets trapped in the pump, and reduces its circulation.
Your boiler engineer will be able to locate the bleed screw on the pump and remove all the air contained in it. With the air pockets removed, the boiler can then be reset, clearing the ER14 fault code in the process.
What other blockages can build-up, alongside airlocks
Airlocks aren’t the only blockage that can occur in pumps. Another thing to check for, is heating sludge and limescale blockages.
Heating sludge is common in most heating systems; it’s broken down rust that falls off the inside of radiators, valves and pipework. It can get lodged throughout the heating system, including in the pump, and cause all sorts of circulatory problems.
Limescale is only common in hard water areas. Limescale tends to attach itself to boiler components such as the pump and heat exchanger. Like heating sludge, it reduces circulation, sometimes to a point where the boiler can no longer operate.
How can blockages be removed to clear the ER14 fault code from my Biasi boiler
The first step is to manually clean out the pump. Once done, your boiler repair company can run a hot flush using chemicals that are specifically designed to clean heating systems; this will get rid of most heating sludge and limescale in the system.
Preventative measures then need to be put into place. To combat heating sludge, a magnetic system filter will need to be installed. To break down heating sludge into manageable chunks that the filter can catch, central heating inhibitor will need to be dosed into the system.
For those in hard water areas, it’s also worth installing an additional product; a limescale reducer. This is going to help catch any limescale circulating around the system.
My boiler makes a humming noise, what could be the problem
As we mentioned above, your boiler engineer is going to want to check that the shaft is moving freely. If it’s not, there’s a good chance the pump is on, making a humming noise, but not circulating water.
Most likely, the bearings have worn, meaning the shaft is stuck, or not moving freely. In general, this problem can be fixed by using a pump repair/service kit. However, if the rest of the pump isn’t in good condition, it might be worth considering a replacement, rather than a repair.
What does my boiler engineer need to check in terms of the pump’s installation
If the bearings on your boiler’s pump have worn out, your boiler repair company needs to determine whether that’s down to old age, or a bad installation.
If the shaft of the pump isn’t horizontal, it’s going to wear unevenly, and wear out prematurely. Assuming the pump is still in good condition, the pump needs to be removed and re-installed correctly to ensure the pump wears evenly.
Why would leaks occur from my boiler’s pump
Serious leaks could lead to low boiler pressure and reduce the pump’s ability to circulate water around the system. If you have a leak on your boiler’s pump, it should be immediately obvious.
You might see pooling of water below the boiler’s casing. Or, as soon as your boiler repair company opens the casing, they’ll see water dripping from the pump.
Pump leaks tend to originate from the seals. Most likely, they’ve degraded over time, and need to be replaced. But it might be that there’s been a catalyst meaning that they’ve worn out prematurely. Anything that has made the pump overwork could be to blame (airlocks, blockages and being on the wrong speed setting).
So, before fixing the leaky pump, your boiler repair company needs to make sure the root cause of the problem has been fixed as well.
What does the PCB have to do with the ER14 fault code
The PCB on your boiler gives and receives signals from a range of components, including the pump. It wants to see the pump is working when it should be and stopping when told to do so. But, if wiring and connections have become damaged (possibly due to water damage), it’s likely the communication between the PCB and pump is intermittent, or non-existent.
Your boiler engineer will be able to test the pump using a multi-meter, and check wiring, connections and the PCB to determine exactly what the fault is.
My boiler repair company is suggesting I buy a new pump, how much is this likely to cost
A pump replacement is likely to cost around £250 including parts and labour. That’s a quality pump from a leading manufacturer such as Grundfos, and the job should take around one working day to complete.
