Baxi boiler, double service mural, forced draft. E35 called parasite
I am not a calderista, I fix electronics, they usually bring me platelets for repair when they are not available or are very expensive. In this arrangement I got involved together with the gasist, I am not sorry, but it does not make me happy either, that is, it happens to be something personal, as soon as I resolve something I will comment, so far I am trying.
Failure in these boilers is very common, with plate change is solved, the repair is a bit complex, but if you are familiar with smd components you can do it.
If you are an electronics technician you have 75% of the solution in your hands, I am an old calderista and 5 years ago a friend sent me to study electronics, at first it will cost you but once you pay the floor right of everything new, you will stop attending other things to devote to this, going to the topic: the spark plug is dual-function, ignition and flame sensor, the operation is simple, it has a start time in which it throws sparks and then switches to sensor, if it does not detect flame, repeat an attempt to ignite like this 3 times and if it does not succeed, it will fail.
Before removing a plate, everything must be checked, especially faston connectors (they are usually sulfated inside the cable lining, and it cannot be seen !!!) and the ground is checked with a 100 watt incandescent lamp and tester. If all that is OK and continues to fail, there if you take out the plate and check the large capacitors of the ignition and sensing stage, they are usually of polyester or tantalum, if you have a capacimeter check them, this is a very common fault in the plate. And the Baxi are excellent boilers, if you play a Peisa there if you are going to renege!
I appreciate your response, and I agree with everything, I do not usually go home, I work only for registered gas operators, but I recognize that this is much better than other arrangements.
A query, the grounding check would be of the live pole with a series lamp to ground, in this case it should bridge the circuit breaker, right? or from neutral to ground.
Specifically in this boiler there is something I do not understand, after completing your routine gives a train of sparks approximately 1 sec. and cut everything by marking E35, if it has a start time in which it throws sparks, it wouldn't be feeling.
Exactly, it is necessary to bypass circuit breaker, but it is the only way (if a telurimeter is not available) to ensure a good ground measurement. In the area of Villa Gesell and nearby to make a boiler walk of these is a multiple birth, since the ground is sandy ....
the fault you comment is typical of capacitors or diodes failed
Over time you will have to make an emulator to test plates, with some boiler in disuse
I ran out of space, I continue. but it is feeling, a plate problem seems sung, I don't know what components are involved in the spark to sensing step, but there is something that is allowing the spark to pass to the current amplifier, the disorientation is that we use three platelets 1 new and two repaired, all accuse the same fault, it could happen that the new one was not so new.
I went with the gasman to test the plate to another boiler, the plate worked 10 points, it also absorbed a pin ground connection near the spark coil, which I had not connected, when connecting that in the other boiler everything worked fine, I recommended that before disconnecting take pictures. I appreciate the help, all your contributions have been very valuable
