Question about Bosch Water Heaters

Fault light flashing 1 flash per second

New board fitted after speaking with worcestor tech help line . Boiler fired up ok . next day after the boiler had been on a while and heated up the house the fault light started to flash . Pressed reset and boiler fired up . This then happened a second time .
Original fault was the fault light was flashing 4 times per second , the boiler would fire up the fan would start then slow down and then stop . There was only 110volts from the board to the fan , this was why the technical helpline said that it was a board fault .

    Have you checked the power to make sure it is properly ground? If the power is reverse grounded or improperly ground boiler control circuit will malfunction.

    Something not adding up here- there should only be a max of 115 volts in system at any point - there is also a 24 and 48 volt on control side . Power fluctuates between 110 and 115 at all times- this is not an indicator of a faulty board. I think -you have to access a couple things - is eye ( sensor )clean? Is there any danger of freezing in lines? Have you had any problems with pump in past and when was the filter last changed- The question I always dred asking are you using dirty fuel? I ask thes questions as the duration of flash indicates no fire detedted in most units and all of the above can cause this to happen

    Boiler runs for 30 minutes then goes into lockout when reset comes back on and does the same

Prior to writing the above fault I had asked the owner to turn the boiler temp controller , for the heating side, down just a fraction . I was phoned this morning to tell me that the boiler had stayed on allnight with no fault light . After consulting with the plumber who fitted the system it appears that there might not be a room stat ,

Boiler,heating and water all working OK but manual override to turn heat on before preset time caused dripping under boiler.Cause and solution?


Did the boiler winter over with the heat turned off and no winterization? If so, then the boiler may have frozen and cracked. Replace it.
If it WAS drained down and winterized, and you just filled it with cold water before firing it, it may be condensation.

After moving my gas meter from inside the home to outside and having a semi concealed meter connected we cant get the combi boiler to work properly we can get hot water and have the gas fire on but


your boiler needs a minimum gas pressure of 16 mb to light successfully. if your gas pipe has been extended it has to be able to flow enough gas. it may need upgrading to 28mm for even as little as a metre from the gas meter. if your central heating works ok when the fire is off then this is your problem

No Heat. Replaced the gas control valve. Pilot burning OK


Try bleeding the gas line to the valve. They are always full of air after a valve replacement. BE CAREFUL!!!!!!!!!!!! Gas is explosive!!!! Does the valve "click" when the stat calls for heat? If not, check the wiring.

I need a diagram for an indirect hot water system heated by a solid fuel boiler and an oil boiler


If you are using more than one heat source you will have 1 more pump than the heat source pumps Main pump = SYSTEM pump pumps through the indirect hot water system and back into itself. This is the system loop. The other two boilers tee into this loop upstream of the indirect tank, downstream of the SYSTEM pump. The cold water return to each boiler tees into the system loop next to and upstream of where the hot water for that boiler tees into the system the loop. The oil boiler will have its own pump on its return line from the sytem loop and the solid fuel boiler will have its own pump. When any boiler fires, it turns on its own pump AND the system pump. If you want a drawing email me -pipesster@gmail.com send a fax number and I'll fax you a drawing.
