BAXI Combi 105E DHW VALVE leak?

Did the job, easy no probs for 3 months now. Bought Diaphram kit £8.00 which came with new brass nut and seal and a small grommit. Switched off water mains/power to boiler and removed front switch and nut(carefull to stop water falling on PCB), cleaned rod and slid on grommit with silicone grease. Reassembled and switched on water and power. Leak fixed!

If its the DHW diaphragm (Faces you on the left hand side) that you are talking about, then all you need to do is turn off the mains water supply and electricity. Open a tap to relieve the pressure and job done.
