P.S: forgot to mention, before tonight I did test with the DHW disconnected, and I got the message error expected: H3: "remove DHW thermistor" "Check resistance at 25deg, 60 deg, 85 deg" "If values not correct, replace thermistor" "If values correct, is there continuity between PCB and...

Hi Agile and Ollski, and all the previous writers. Thanks very much for your continued support and I'. The first thing I,ve done this evening is to dismantle the valve which was a bit sticky, and did'nt spring back completely into DHW position. I cleaned it and now it ioperates as it...

Hi Tony, I switched the water main off and then swicthed the boiler on again. The diverter goes into the CH, then back to DHW position (Forward). The display shows "D" and get stuck there the burner display is flashing, but there is no ignition process any more. If I move the CH...

Hi Ollski, Thanks for your reply. :) When switched on, the display goes straight from "S" to "D", no "T" displayed at all at any point, ignition proceeds,gas flows OK, then after a few seconds gas gets cuts off, the "D" sign stays on, and does not go back to "0". According to the...

Hi Tony, Point taken about second hand bits. In fact it turned out the second hand PCB and dispaly panels didn't solve anything. And I get exactly the same fault whether I use the new or old ones... Which means I've got a couple spares, just in case... or they both have identical faults.Not...

Hi Tony, :D Thanks for your reply. I will follow your suggestion to cut the water off to make sure that there is no demand, and start the boiler again. I'm also wondering about the DHW sensor. Is this the sensor you are talking about?. As mentioned previously, I measured the resistance...

Hi BDL, :P You're right, so far I spent about £100. I managed to find a spare PCB and dispaly unit from a plumber whose customer decided to get rid of his ideal boiler and replace it with "a proper one". I wonder why... While it was on warranty, I had to call IDEAL engineers... 7 times...

Hi Ollski, Thanks again for your reply. When I switch the boiler on, the indicator goes from "S" to "D", and the diverter travels from a medium position to the CH position (As per the manual's drawing),the boiler fires, then switches off and then back to medium position, and sometimes back...

Hi Ewan, You'll be able ro adjust the level of your units with the scrwe in feet, no prob. But the reason for having a level floor is so that when you put the skirting board inder the units, it's flush with the units and the floor without unsightly gaps. The wall units have got adjustable...

Hi, I've installed an IKEA kitchen a couple years ago and was very pleased with the quality of the units. I cut 2 solid 40mm beech worktops with a hired router and jig. It was a first time so I took great care to get the measurements right. It would have been quite an expensive mistake...

:) Hi, Ollski and Chrishutt. thank you for your very fast replies! The flow sensor gives correct reading. Tomorrow I will certainly look at the positioning of the flame sensor and I will also check the flame spreading and electrical wiring continuity. The interesting thing is that the...

My boiler switches on/off erratically. When HW tap runs, boiler sometimes switches on but cuts off right away. CH doesn't start at all. I've changed the PCB, the display unit, the flame sensor (Slightly damaged). and the overheat control temperature sensor (Couldn't get recommended resistance...
