The diverter valve has been replaced the hot water worked fine for a week but has now gone luke warm again. Does anyone have any suggestions what could be wrong?
Check your expansion vessel is not flat.if so recharge..simple way to check press in valve on vessel if water comes out or little air recharge..if water still in vessel the diaphram in vessel has split so replace vessel?hot water relys on expansion??

the problem is the diverter valve unit, source a corgi engineer to fit new one, cost for valve approx 80 quid +fitting

vailant boilers are one of the best on the market and should last you more than 6 years depending on installation and servicing.
the engineer you had should not have replaced the diverter valve if the boiler was firing up when the taps are opened. if you was getting luke warm water with the boiler alight it is a classic symptom of a blocked plate heat exchanger on the central heating side.
a new heat exchanger can cost around £100 depending on the age and model of the boiler.alteranatively it could be descaled but may clogg again. it would be a good ideal to fit a magna clean filter on the system to help prevent further debris if you have a dirty system .if you don't trust your engineer i suggest you ask another. find out if he is registered first and don't pay until you are satisfied with the work. if you are asking the same engineer back try and get a discount off the work as he has failed to rectifiy the original fault and fitted the wrong part due to wrong diagnostics. if he is registered you can complain to the governing body ie corgi or gas safe register.
good luck.

it sounds like your shut off valve might be bad even though it turns on and off by turing it doesn't mean that the washer is not stuck to the seat and not opening, try replacing the valve

Check to see if diverter valve is in domestic mode or heating mode.
