The aforementioned unit was installed in 2014.
Two days ago on switching on, nothing appeared to happen, did not activate, none of the normal lights appeared.
I switched off at the mains, and switched back on, and everything functioned as normal
The following day on switching on, nothing happened, and after switching off, and switching back on, all the control panel stayed off. The delayed time of a couple of hours when switched off before switching back on was tried, but was unsuccessful.
On closer inspection, it was noted that when looking from directly above the control panel, a series of LED's were flashing.
1 above the Activate/ deactivate switch
1 above the Stop & Go switch
1 above the lock/ unlock switch
2 above the activate/ deactivate outer ring
4 above the Timer
2 below & one above the deactivate & activate the extreme right outer ring

Can anyone please advise what the possible problem could b?
