BAXI barcelona
I have installed many of them and encountered many problems. Baxi do not honour thier garantees and this boiler has destroyed thier reputation.
The main problem with the unit is the condensate trap and this screaming.
Due to imperfections in the castings of the heat exchanger , localised hot spots occur which causes a screaming noise through whats known as kettling. this in turn oxidises the heat exchanger surface which leads to the deposits of aluminium oxide in the condensate trap. eventually this will lead to a hole in the heat exchanger. Baxi will deny this but its true.
I have changed two of them which flooded my customers houses free of charge. The other problem with lock out is caused by the condensate trap
in that when the levell of water is about to discharge , condensation on the top surface of the trap makes contact with the electrical probe and locks out the boiler. this is a safety device in case the condaensate drain gets blocked. This problem is exasperated by two other design faults.
The first is the oxidation of the heat exchanger and the resultant oxide sludge which buils up in the trap, this can get invaded by micro orginismns creating a sort of jelly which gums the trap up. The second problem is that unless the working pressure at the gas valve is at 18.75mb
the boiler will suffer from explosive ignition which causes a sudden increase in pressure within the trap soaking the sensor probs resulting in lock out. A simple remedy for the problems associated with the trap would be to lower the central deviding plate in the trap and thus lowere the average levell of water. Again dont even consider talking to baxi , I have stoppod using thier products and I can only say they have cost me dear and that I would never use them again. HOPE THIS HELPS /Got up today and my baxi is at lock out , well suffice to say it was the temperature sensor on the flow pipe , easy to change there are two of them at the top of the boiler when you remove the casing you can see them, one black and one red,cost £ 12.00 for two. Another thought occured to me that it seems people are changing thier pcb,s for a past time. The cuase of this failure is probably the continual lockout due to the condensate trap design. Its like switching something on and off several hundred times, it don,t like it. for those of you who are technically minded if you get a fault , phone baxi service number and speak to technical, I know the boiler is useless but at least you might be able to squeeze some more life out of it.
Hi Tim , unfortunatly you have to fit a new flu . Use a vaillant boiler they are the best and you can get a grant for the ecomax one of £300.00. if you have any questions I will answer them to my best abillity cheers, uncleben.
