if this occurs when the unit is in use for only hot water, there will be an internal leak in the secobndary heat exchanger, you will have to replace it. check first that the charging link has been removed when testing to ensure it is not passing.
if it happens when the heating is switched on then check the presure in the expansion vessel ( dump all presure from system and use a car foot pump with a gauge there should be 1 bar presure) that is the big red thing behind the pump, if water comes out of the test valve on the front of it when you try to test it or it wont hold the presure you will have to replace it (a nasty job you have to strip half the boiler) if you can pump it up make sure you release the presure in the system as you pump it or you will get a false reading

Do you have an inducer on this unit? If you do, it could be the pressure switch not opening or closing properly. Also, check for any limit switches that might have tripped that you need to reset. Some limits are automatic reset and some are manual. Also, check for a reset switch on the unit that is used when the power gets cut un expectantly. You can do a little research on the unit also using the model number and brand of unit on-line to find a user manual that might have some trouble shooting guidelines.

There is a 15mm pipe from the pressure relief valve which should so through to the outside. These valves are prone to leak after time. Look at the end [outside] of this pipe. Wet = leak from valve
