Timer and operation light flash similtaniously 5 times then 5 second gap then flash again. continues when turned off by remote but no heat. Manual says "immediately stop operation and consult authorised service personnel". Did this, they unsure and say turn off at isolating switch for one and a half hours then try again. Third try this has worked but did it again and again two tries before starting, going okay presently. Any ideas what this code is advising?
