SOURCE: Vaillant Ecotec combi boiler -

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.

You can probably go online to the manufacturers websit to their tech support you will probably find downloadable documents for the unit. I would look them up myself for you but you didn't list the brand or model number. Hope this answers your question.

IF the weather is extremely cold, and you're getting F28, the external pipework may be blocked with ice. Warm up the external pipes (lag them if you can) - and now see if your boiler will re-ignite.

A friend fixed our condenser boiler with this tip - hope it helps you.

I have a honeywell cm927 control unit, and the red light on the receiver keeps flashing. i can manually turn the boiler on and off at the HC6ONG receiver. i've tried the faqs in the manual but to no joy....


The red flashing light means that there is an issues with the RF comms between control unit and receiver. You can reset by switching the boiler off and back on and then re-sending the temperature signal. You need to check batteries in you thermostat and also the position as the signal could be interfered with or it may be too far away from the receiver.

Hi i get fault 28 on my vaillant boiler


F-28 is a common error for my vaillant. I have had this problem serviced at least 10 times (all under warranty). It is an ignition problem and can be connected to a number of things. I have had the starter electrodes cleaned only to later have them replaced(4 times). I just had the "panel" replaced yesterday (looks like a motherboard or electronics panel). This is the second time to have this replaced. All of these things can give you an F-28 error message. I have an atmotech pro and have had ongoing F-28 issues for two years. They are looking at venting/air issues as well to see if this is the problem. douglas
