As the problem continued a few times each week, I've got closer to identifying when it happens.
If someone takes a 10/15 minute shower, the boiler works fine. Then, if another person takes a shower within 2 or 3 minutes, then things are usually fine as well. HOWEVER, the problem arises when someone tries to take a shower 15/20 minutes after the last person. At that point, the boiler DHW demand indicator light comes on but the Flame detection indicator light fails to come on & the boiler fails to ignite & provide hot water to any shower or tap in the house.
Wait another half hour, & all is fine again.
Any ideas ?
