Thank you for your help in advance. We recently report that there was a fault with our washing machine, the landlord duly arranged for an engineer to visit. the fault identified was a blocked filter. One week on we have received an invoice from the landlord for the call out fee and a brief letter explaining that as the machine hadn't broken down, it was not their responsibility to cover the costs. I have two issues the first is we weren't informed of any potential cost on our part and secondly there is no manual in the property to refer to for maintenance and no easily identifiable model number etc. Ultimately can they enforce this invoice. Thanks Again.
