i am 100 per cent sure. all i know is that the boiler does light up for 1 second and stops and repeats this 3 times before displaying number 10. i see it light trough a pipe glass hole. any ideas
please can you help me.
i have a vekera 35 he. and it will not work. it is flashing 10 0n the front panel. i have had a local plumber out to try and fix it. he charged me to reset it and then to teld me he would be back next day with a part. guess what he never came back or ansered my calls...
