What should the pressure be on a glow worm boiler?
between 1 to 1.5 bar
The boiler should read between 1 to 1.5 bar of pressure when the central heating is cold. If this drops too low, below 0.5 bar for example, this normally means water has been lost from the central heating heating system and the filling loop must be used to replace this water.
What are the problems with the glow worm boiler?

How to fix glow worm 30cxi boiler F1 fault?
I had F1 first off when my bottled gas ran out, then after changing the bottles F1, F1 and then it changed to F4, As some one posted here, just keep pressing the reset button and it works great. Good luck all. tried bleading rads will do system tomorrow still no luck tho did get an extra half an hour out of it and now have f4 fault anyone know?
Is the Glowworm 24hx boiler good for F1?
Great service from Glowworm once we called for their support. One issue is that the plumber is not familiar with this level of detail with the boiler – OK with pipes and installation though. I tend to agree with the reliability. I now get F1 on my exactly 13 month old glowworm 24hx.
What does F9 mean on a glow worm boiler?

Once the pressure is back up to around 1.5 bar, your Glow-worm boiler should have sufficient pressure to work again. Increase the pressure too much (above 2 bar) and you’ll then have a problem with high boiler pressure, which could damage the unit.
What should boiler pressure be at 3 bar?
Anything above a boiler pressure of 1.5 bar isn’t ideal. 2 bar starts to become more serious and when most boilers hit 3 bar, they’re in the red zone on the pressure gauge. So, the unit is likely to lock out and display a fault code. If this happens, I’d suggest speaking to a Gas Safe boiler engineer. Why Boiler Pressure Rises
Why does the pressure on my Glow Worm keep rising?
Since refitting the radiators and topping up the system back to 1.0 bar there’s an issue with the boiler (Glow worm 30cxi) – even with the blue filling tap closed tight, the pressure gradually increased to what I assume was >3.0 bar then the pressure release valve discharged loads of water.
Is it normal for boiler pressure to be over 1.5?
A combi boiler pressure gauge reading over the 1.5 mark whilst the heating is in full operation, is likely normal due to the water demand being placed on the boiler so it’s likely nothing to worry about. In this instance, a reading between 1.5 – 2.5 bar can be considered normal.

How to increase the pressure on a glow worm flexicom?
To increase the pressure first make sure that the heating controls are switched off. Next turn both grey taps under the boiler a quarter turn to the right until they stop. The pressure can now be seen to rise. When the pressure reaches between 1.0 Bar and 2.0 Bar turn both taps back in an anti clockwise direction.
What is the sweet spot for boiler pressure?
Nobody actually knows, but it seems to work as a measurement. The boiler pressure sweet spot – usually marked in reassuring green – is between 1 – 1.5 bar. Anything under 1 bar and you’re suffering from a boiler that’s losing and/or lost pressure.
What is the fault code on a flexicom glow worm boiler?
Fault code F14 (Flexicom CX range) If you were to look at the service manual, you’d find this fault states there’s a defective gas valve. However, check there is power from the PCB to the gas valve. If not, it’s not the gas valve at all, but either the PCB or the wiring harness.

However if it is not closed it will slowly leak additional water into the boiler. This will increase the pressure and the boiler will lockout. Note –If there is no filling loop in your boiler, they might be installed on the cylinder. If you have re pressurized your boiler too much you will need to drain the system.
What to do if Your Glow Worm is gaining pressure?
Turn off the power to the boiler so’s it doesn’t fire up for any reason (pump anti-seize, etc). Turn off the flow and return CH pipes under the boiler – there should be quarter-turn valves fitted. See if the pressure still increases. If it does, then it’s unlikely to do with your radiator circuit.
