intermittent lockout is THE most common fault on a baxi barcelona.
When first firing up;
1. Electrodes are prone to burning out, check and replace as necesarry.
2. Spark weak and intermittent, PCB has been modified to make the spark more reliable
When running for more than a minute;
1.Condensate trap/pipe blocks up, proving the condensate discharge sensor, locking the boiler out. Disconnect the lead to trap temporarily to determine this. Some syphon traps were machined/formed incorrectly, the inner bore on the syphon has a burr towards the middle of the tube, thus restricting the condensate flow. Make sure the syphon sensing tags are fixed with metal screws and not plastic, as some were made with pastic pegs meaning poor contact on the syphon leads. (part number 244157 - screws)
Also, where does the condensate pipe terminate? Is water back flowing up the condensate pipe into the trap, i.e. from a soil pipe, ventilated stack? Is the pipe clear, does it fall continuously away from the appliance?
2. Faulty combustion case seals, products of combustion leak out, spilling onto overheat sensor thus the ambient tempeature around the sensor increases causing the boiler to trip out.
Part numbers
modified condensate trap 247015BAX
seals 242482 and 242483 and 242489
