Thank you for your feedback. It turned out that the dryer had been switched off at the plug just above the machine, not sure if you had done this by accident but all is working. There are two separate buttons to switch the fan on and off, this may have caused confusion as I know normally it is the same button for both. I will take this onboard and add a note to the instructions. I have spoken to my cleaner and they apologised as they had thought they turned the dishwasher on. As you will see from previous reviews cleanliness is usually rated very highly, I place a lot of importance on the property being cleaned to a high standard so I apologise if you arrived at the property to anything less. I have had pest control go to the property and there were no sightings or droppings found. We have taken precautionary action just in case. I hope you can understand the refund was only rejected based on the amount requested.
