Expansion vessel needs repressurising

You would not have to search very far to see that this is a problem with the expansion vessel.

This is why we ask that you read the FAQ first as most common problems are covered.

Look in FAQ at the top please!

I am sure that you have!

However I am also sure that you have NOT done it in accordance with the instructions.

Please do it as instructed!

HAVE REPRESSURISED TO THE LETTER AND IT STILL RISES. IT'S NOT THE FILLING LOOP AS IT ONLY RISES WHEN THE HEATING COMES ON

.THE BRAIDED HOSE FROM THE EX VESSEL WAS BLOCKED AT ITS CONNECTION AND AFTER 6 MONTHS IT WORKING PROPERLY AGAIN!!!

THANKS TO HARROGATE!!!!!

If it has been correctly repressurised then the communication pipe from the boiler is blocked.

But you seem to know that already!
