Hello all,

Hope someone can answer my question as I am quite concerned. I have a Worcester 24CDI combi boiler that had a pressure problem last week. The bar was down to zero, and I could not manually adjust myself as the tap to turn up the pressure was firmly wedged. I called out an engineer who adjusted this and turned the pressure up to 1.5-2. Unfortunately this has made no difference to the water pressure which switches between luke warm to cold when the hot tap is on every 10 seconds or so. The pressure is also lacking still.

I returned home from work this evening to find a huge puddle of brown sticky fluid underneath the boiler. It has splashed all up the skirting board, there is a lot of mess! The engineer said that he cleaned up some of this sticky goo as there was a small amount on the bottom grill of the boiler?? He said to keep an eye on it but didnt really explain what it was.

Does anyone know what this could be? I will call the engineer first thing in the morning but I am too scared to turn on the hot tap or heating just incase!

Your help would be appreciated. Many Thanks,

Sarah

pressure in boiler (which is shown on gauge on front of boiler) has nothing to do with pressure coming out of taps, if that whats you were getting at. if pressure is on 1.5 - 2 bar with heating off and cold its a little high. 1 - 1.5 cold is good. The gunge from the boiler could be coming from a auto air vent inside boiler which is stuck open a little or if pressure to high a seal may have gone. If the brown fluid is heating water your system needs washing out. heating water if treated properly should be clear. As for water going hot and cold you will need to get someone in who knows about worcester boilers. If any trouble call worcester, they will put you in touch with a engineer in your area.
