Check the electricity setup
First, please check that your electricity setup is able to support the use of several machines running at the same time. If you are sure that your electricity setup is not the problem and your tumble dryer is the reason why your electricity is going down, we recommend booking an engineer appointment to have your dishwasher inspected. If you notice a leak, please report this to the engineer when booking an appointment, or if you choose to book online, please add it to the fault description.
If the drying programme was interrupted by a power failure, restart the programme or remove the laundry and spread it out.
