Ecomax 835 boiler

Our landlord recently installed an ecomax 835 boiler in our student digs after our old one nearly killed us. However, we are now having problems with the new one. namely F22, F23, F24 which the manual claims means not enough water in the system. however the guage is on 2 so this seems unlikely.
central heating is generally working ok but hot water will only come on for a few seconds then goes cold again. My housemates say they've also got an F0 before and we have no idea what that means.
I was wondering if anyone has had a similar problem and if you have any advice.
Thanks a lot

If the old boiler really "nearly killed you" then it should have been reported to the HSE !!!

As tenants you should have a landlords Gas Safety Certificate for the property!

The boiler should have been installed by a CORGI registered person and he should come to sort out any teething problems.

It sounds like a water flow problem and it may be that there is air in the system. Perhaps he has wrongly left the auto air vent cap fully tightened?

Nearly killed us is possibly a bit melodramatic-just set off our carbon monoxide detector, it was properly disposed of and the new one was installed by a CORGI man. I guess we'll just have to get him back in to check it over. thanks for the reply

The common fault with all these F codes is the Flow NTC faulty coupled with possible air in the boiler.

Probably wasn't commissioned properly with the self purge program.
