WORCESTER BOSCH BOILER LEAKING, LOSING PRESSURE, SPRAYING WATER OUT THE BOTTOM, IT'S BECOMING ALL TOO COMMON.
This blog post was just really to bring to peoples attention some of the issues we've been getting on a pretty regular basis now with Worcester Bosch boilers. I can't speak for the newer boilers that are still under warranty it seems to be when they hit about 7 years old. So we are pretty much getting called out on a weekly basis now to a Worcester boiler leaking water, it seems the main hydro block which is the water carrying parts are made of plastic, over time there are beginning to perish and there are two parts in the boiler that are affected the most one is on the left-hand side of the boiler. This part usually pin holes and starts spraying water out, this can cause a loss of pressure and you may find yourself topping up every few hours. this same part is on all the models of Worcester boilers we now carry these as van stock and the repair usually costs around £200 and includes a service.
The next fault and probably more common is on the cold water side. Worcester say that this one can be prevented by installing a small shock arrestor on the cold main this acts as a shock absorber when the tap is closed. the leak its self-seems to come from the flow turbine they have usually completely perished by the time we come to remove them. we tend to replace the sensor at the same time to save disturbing it in the future. It's a pretty straightforward repair and again something we try and carry as van stock and this repair usually comes in at £220 with a service.
