PH Jones troubleshooting guide
There could be a number of reasons why your central heating or hot water system is not working.
Please try these tips first:
Check that the gas, electrical and water supplies to the heating appliance are turned on. It's surprising how easily they can get accidentally switched off.
If relevant, check that you have sufficient credit in your gas and electric card meters.
Check that the room thermostat is turned up and the clock timer/programmer is switched on. Remote thermostats have an override buttons, press for a few seconds and see if this helps.
Try putting your heating on maximum for a short while to see if you can get it back into action.
Has the system pressure dropped? A water pressure indicator can be found on the front of most boilers, they are either a dial or a digital display. The indicator should read between one and two bars of pressure, if it is below one then your boiler pressure will need refilling. Here are a few simple steps to refill the pressure in your boiler:
Locate the cold water feed to your boiler (this is normally a plastic tube located either next to or under your boiler)
Find the small tap on your cold water feed and gently turn until your boiler pressure indicator display reads between one and two
Once it is between one and two, close the tap. Check to see if your boiler is working again
Has there been a power cut recently? Your heating clock programmer may have returned to its factory settings when the power came back on. Test the central heating by setting it to come on in 15 minutes time - if that works, simply re-enter your preferred settings.
Do you have a reset switch? These are usually found on the front of modern boilers. Please check your appliance user manual to see if it needs resetting.
Try turning the electrical supply to the boiler off and on - the switch is usually near the boiler or in the airing cupboard. This might reset your boiler and resolve the problem.
Are other gas appliances affected? If so the problem is bigger, you will need to contact PHJones, so that they can then make a mutually convenient appointment for an engineer to attend.
Do you have an immersion heater? Some heating systems with a hot water cylinder may also have an immersion heater fitted as a back up to the heating appliance. In the event of a boiler failure, you can switch on the immersion heater via the spur switch / timer that is usually located within the same airing cupboard space. Please remember to switch back off once the heating appliance is operational again.
What else could be the cause? In long periods of cold weather, the condensate pipe of your boiler - a waste pipe that carries condensation from the boiler to your drain outside - can freeze, especially if it's exposed or incorrectly installed. This can leave you without heat and hot water as the boiler has an in-built safety device to prevent any damage to the system.
Bleeding your radiator - Air inside your radiator can stop it from working, giving the impression that your central heating has broken. Follow these simple steps to bleed your radiator.
Locate the valve at the end of the radiator (round valve with square screw groove)
Using a radiator key, turn the valve carefully until you hear air being released. It might
be best to have a cloth in your hand when doing this to prevent dripping on your floor
or thermostatic radiator valve
Once the valve starts to drip tighten and close it
Check your water pressure on your boiler after doing this
Checking your thermostatic radiator valve -If your radiators are cold it may be because your thermostatic radiator valve is set to low. A thermostatic radiator valve is located near the bottom corner of your radiator. It is a cylindrical shape with numbers on it (normally ranging 1 to 5), the higher the number you twist the valve to, the more hot water will be let into your radiator.
Follow these simple steps for the thermostatic radiator valve:
Check if the boiler power light is on
Locate your thermostatic radiator valve
Make sure that nothing is obstructing it as they detect the temperature of the room
Twist the valve to a higher number to allow more hot water to flow into your radiator
If you do need to call PHJones to arrange an engineer, please have the following information to hand:
Boiler make and model.
Are there any error codes (Beginning E1 or lights flashing)?
Do you have any other forms of heating (fires, heaters etc.) or hot water (Immersion heater/ electric shower)?
