Incompetent and Inexperienced on Modern Dishwashers (especially Miele). After reading several good reviews we thought Glotech repairs would be a good choice to look at an F25 fault on our Miele G7102 Dishwasher. It had given us excellent results on daily use over the last 30 months. We gave all the appropriate fault code make/model/serial number data to the call centre when making the booking, so we expected a good outcome from the visit. The Glotech technician attended on the day and at the time agreed, however he readily admitted that he had never seen a "Miele Dishwasher and really didn't have a clue". He plugged in a wall mains socket tester, that confirmed out kitchen ring main was in good condition / safe. He then laid the machine on the floor and removed the bottom panel. Unfortunately this put water into the circuit board area. Miele confirmed that NONE of their dishwashers should ever be laid horizontal for this very reason. Without doing a single electrical test he made a list of new parts that would be required and left. We then received an invoice for his "investigations" together with a long list of parts required. Luckily both my wife and I are electronics engineers and realised our mistake in asking Glotech Repairs to have a look. We then contacted Miele who quickly rectified the problem, after drying the PCB's. The machine has worked faultlessly since. We refused to pay for the Glotech technician, as he didn't know what he was doing, potentially damaged our machines delicate electronics and basically listed every moving part in his "diagnosis". We have explained our reasons for not paying in three phone calls and eight emails. Today we have received threatening letter, with an inflated £25 charge for debt collecting and more charges to follow. To avoid the incompetence of this technician, wasted time, delayed repair and potentially expensive litigation We suggest that you go elsewhere for your repair. Date of experience: 27 July 2023
