Hello. My question is stated in the title of this posting, but here is some background to my question:
In March of this year, I posted on this forum about an intermittent fault on our Vaillant Combi boiler (it's an EcoTech Plus 824). Many, many times, in the morning, I would rise and turn on the hot tap, only to find that the water was cold — the ignition had failed. I kept on pressing the fault-clearing button, but it did not cure the problem.
One day, I was pleasantly surprised to find that the ignition had not failed for two whole days.
Time went by, and the last entry in my diary (about five days ago) says that the boiler has been OK for 21 weeks. I began to believe that the intermittent fault had finally been cured (by holding in the fault-clearing button for a long time, perhaps).
Anyway, this morning, the same old problem appeared. The DHW was cold (as were the radiators), and the fault shown on the display was that the ignition had failed.
The reason for this rather long-winded post is that, about five working days ago, construction engineers, working only about 50 yards/metres away, commenced pile-driving. As the drop-hammer drives home the piles, the house shakes (I am very concerned about the effect that this will have on the building, but that is another subject). Anyway, I was wondering whether this vibration might have an adverse effect on our boiler, and whether this may have been the cause of it failing. This morning, it took about ten re-sets (pressing in the fault-clear button) to get the heating icon to show steadily, instead of slowly flashing in and out (the last-mentioned always tells me that the heating has not been set properly).At this moment, the DHW really is hot, the rads are on, and I am keeping my fingers crossed.
Of course, I am seeking reasons to blame something other than the boiler, and hope that my suspicion that vibration has caused a malfunction will be supported. That would give me more faith that, in the Spring, my boiler really was cured.) Please tell me what you think, and any reason you may have for bearing out what I think.
Any comments about this would be received with interest. Thanks in advance!
