SOURCE: radiant combi boiler put hot

either defective sensors, or check the flow temperature going into the plate heat exchanger, if this getting very hot, but not circulating out the other side, it will probably be a blocked or restricted - replace

SOURCE: Vaillant combi boiler problem

when the tap is turned on and the water light on the boiler doesn't this means the diverter valve is not operating it could be down to low water pressure in the house this can be checked at the cold tap in the kitchen. if there is plenty of pressure then it could be the diagphram in the diverter valve is worn or split. the diagphram is only a few pounds but it depends on the engineer you get as to how much money he wants to fit it.
the egg timer symbol (or two pyramids together) is an ignition indicator turn off and on again to see if it will fire with the tap running. reset the boiler with the lower right hand control knob.

Hi,

You need to get a qualified 'Gas Safe' engineer to check the Venturi in the flue, and clean it out. The other thing to look at is the igniters, clean them wirth emery paper as this boier relies on flame rectification (ignite and sense flame)

The other important aspect which also hasn't been mentioned is to check the inlet and working pressure (as i have had a faulty gas meter governor before)

Quite often the simple faults are overlooked and everyone goes for the PCB, It is doubtful it's a loose wire on the gas valve, The best advice is to get a gas engineer in and for him to call Halstead while on site.

Be very careful when working on your own gas boiler, as any mishaps, and your house insurance is void.

Boiler won't light you here fan kick in then light comes up red on b can anyone help please?


First try to ignite the pilot light yourself. Instructions for igniting your boiler can be found in your boiler's manual or sometimes in the inside door of the boiler. If your boiler's pilot light won't ignite, you either have a gas supply problem or you'll need to call in a Gas Safe Register approved engineer for a repair.for details click

My aristion DIA 20-24 combi boiler keeps tripping the over heat thermostat button located under the main control panel maybe 5 times a day seems to be getting more frequent


hi,

just check your water supply of your aristion DIA 20-24 combi boiler if is in constant pressure. not properly circulated water supply can cause overheating.

and manuals can help us also in proper checking. at the link below please check this out if you don't have.

My Worcester Bosch Greenstar Combi boiler digital display has started flashing the temperature then two half-rectangles alternately ... it is not heating the radiators to full capacity - any ideas?


just had same problem.  this apprently happens if the power supply has been interrupted or you switch the power on and off.
• The boiler runs for 15 minutes at minimum heat output to fill the condensate trap, the display (K) alternates between -II-” and the boiler flow temperature. This occurs every time the mains supply has been interrupted.

I have a 6 year old Halstead Ace High boiler which has many recurring problems due to a bad fitting. It was never flushed out causing the heat exchange needing to replaced TWICE through clogging and then...


Firstly your system needs a power flush to get rid of the grot, then it needs a good inhibitor to slow up the reappearance of the sludge.

Changing the boiler won't help. Any boiler will get clogged up but the halstead DHW heat exchanger is particualrly prone to getting gummed up. You can clean this out and refit without having to buy a new one. - but without a power flush it will happen again.
