Ideal ISAR m30100 PCB settings

[eddmulholland]

I had my PCB replaced about a month ago and since then the boiler has pressure problems - losing varying amounts of pressure (from 1.5 bars to 0 in 24 hours usually). I am wondering if the PCB setting links have been incorrectly inserted. The person who did the job has been really poor at getting back to me and now claims to be on holiday.

Where can I find which links should be inserted for a m30100 model? The instructions contain options for many boilers but not that particular model. Thanks.

Pins 5 and 3 should have links on,no 5 being closest to the connector for the user display.
When the boiler is switched off at the control on the front panel the back on again,the display should flash a number 5,thats the code for a M30100

In any case the loss of pressure will have nothing to do with correct pin links,you are losing water somewhere.

Pressure problems are certainly nothing to do with pcb link positions... the boiler just wouldnt fire if they were wrong , it just throws up an error message on the digital display.
If no obvious system leaks around radiators and pipework etc check you arent losing it through the prv to outside hence suggesting an expansion vessel problem .
Failing that Ive condemned a few of these Isars old and new types to the scrap because of heat exchanger leaks which just pour down the condense drain unseen........ good luck!!
