Worcester Bosch Low Pressure on a Combi Boiler
What is Low Pressure on Worcester Bosch Combi Boilers
we will look into the causes behind the Worcester Bosch Low Pressure error and explore potential solutions to resolve it.
Worcester Bosch Low Pressure
Low Pressure on a Worcester Bosch Combi boiler indicates a fault in the sealed system pressure reading on the boiler which should normally read Between 1.0 Bar and 1.5 bars on the pressure gauge dial.
This should be done when the system water is cold.
You are able to view how much pressure have by looking at the pressure gauge dial located on the front of the boiler normally on the right. Having low pressure can prevent your boiler from firing up to produce hot water and central heating and in some early worcester models that do not have a low pressure switch this can cause serious damage to components in the boiler.
Topping your worcester bosch boiler via the filling loop with the filling normally resolve the issue
Possible Causes of the Low Pressure & How To Fix It
Why Does The Worcester Bosch Boiler Low Pressure Keep Happening?
Periodically over time due to the heating and cooling over time the water will dissipate away out the microscopic joints in your central heating system. The time this takes varies from each central heating system but I have found from experience it happens more often on systems with plastic pipe. You shouldnt really have to be topping up the water via the filling loop, more often than once or twice a year. Although I have known some central heating systems to have not needed topping up in over 4/5 years it really does vary from system to system.
Other Common Causes
A Cracked heat Exchanger inside the boiler.
A Faulty expansion vessel within the boiler.
A faulty pressure relief valve withiin the boiler.
A leak within the boiler on another component.
Leaking pipework on your central heating system.
A leaking Radiator.
A leaking Radiator Valve.
All these faults above will cause your Worcester Bosch Gas CombiBoiler and central heating system to lose water pressureiver time causing the Low.
Why IS There No Fault Or Error Code on my Worcester Bosch Boiler.
On the early Worcester models of the Greenstar, The Cdi Classic & the Si models there isnt a pressure sensor. So the boiler has no way of telling you if it is running on low water pressure.
You would have to ask Worcester Why that is, because a Combi boiler running low water pressure isnt healthy for boiler longevity.
On later models Such as the worcester 2000, 4000 & 8000 A low pressure will appear on the fascia display Screen.
Fixing the low pressure
The first thing would be to check your pipework, radiators and radiator valves.
If you cant find a leak on your central heating system then you should contact a gas safe registered engineer to investigate the problem to get it resolved in speedy fashion.
They can diagnose diagnose the specific cause of the error and take appropriate measures to rectify the issue The solution may involve replacing faulty components.
Whilst filling your system up for a few days will be ok till an engineer arrives.
If done continuously over time it cause other issues such as blockages. The continual filling of fresh oxygenated water will cause the system to foul up with rust. If left unchecked over time can cause other components to fail in your boiler causing more expensive repairs and time without heating and hot water
How do I get this fault Fixed.
You will need the service of a registered Gas safe Engineer.
