It seams the valve that senses water flow is not operating properly,causing the boiler to keep heating the water when it has nowhere to go,i,e the taps turned off,thus boiling the water.

We have a Worcester Bosch Highflow 400 (10 year old) combi boiler. Over the last few weeks when we have put on the heating the boiler kicks in and fires up and the heating comes on (the water comes on fine...


The by pass pipe may be limed up. This apparently causes a reduced flow which will stop the heating side of the thing working. Call out Worcester Bosch engineer. It costs £210 including VAT and most parts and they almost guarantee to get it working.

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.

Boiler bangs when hot water used


You need to install a "water hammer arrestor" they can be found at any local plumbing supply house.

If you can find one with "Shark bite" fittings already installed then there will be no need for soldering or special tools other than a tubing cutter.

Vaillant Ecotec combi boiler - radiators working but no hot water flow to taps


David,

The fact that you're getting a little burst of domestic hot water suggests that the boiler is capable of circulating hot primary loop water through the heat exchanger, but doesn't necessarily do so when it needs to.

What seems to be lacking is a recognition that domestic hot water is now being drawn off, and that the boiler needs to fire up and divert the primary flow through the heat exchanger.

A good place to start might be the flow switch (usually in the bottom of the boiler, where the cold water supply comes in) or the electrical connections to it.

I want to take a sink unit out. This means I have to turn off the cold water mains and hot water. I have a Worcester combi boiler and am not sure how to turn off the direct hot water . Can you help


Under the sink itself there should be shut-offs. To turn off the water to your boiler, first turn the power off to it at the breaker box. Then on the boiler itself, there will be some valves. One of the valves will be located in the copper line that comes from your water meter. Turn that one off. If you want to turn off the water to the whole house, right next to the water meter there should be a valve. Turn it off and open all faucets to ensure the water is off. Reverse this procedure when establishing water pressure again.
