Hi I had a vokera Compact 24 installed in June 2003 and within the first year I had a Main Circuit Board replaced and some sort of valve replaced that was leaking. All covered under Vokera's 1 year warranty, but in fairness you shouldn't expect many problems within the first five years realistcally (Should you? !!) Last week we stopped getting any heating or water from the unit, but the green light continued to flash, indicating no problems. The plumber opened the unit and it fired up, indicating a air pressure switch problem? He replaced this and it still refused to light, so the next test indicated another faulty circuit board. When he replaced this it still refused to light, so he looked further to find he'd put a pipe on the wrong way round on the air pressure switch? when he swapped it round it fired up. (This was last night) Within an hour the red light came on, which I reset and it worked fine. Today we have nothing, and every time you reset, the red light comes on. Any thoughts? So far it's cost me £130 and I still have no heating or hot water, a 3 1/2 year old and a 7 month old and a miffed off wife. HELP!!!!
