Hi my name is ***** ***** I'm here to help you today. Would you kindly let me have the PNC number of your appliance from the rating label down the door side and also put the appliance on the hottest wash program and confirm that it is heating the water
OK that is fine there are only two versions of this model so we should be OK. When was the last time you put a cleaner/descaler through it?
Go to Tesco and by a packet of Oust - it'll be about £1.50 or there abouts. You get two sachets just follow the instructions - then come back to me when you are done.
