Good morning, my name is ***** ***** I will assist with your query today.
Hi David, E16 relates to a fault in the heating system, which the majority of the time means a new element is required.
The replacement element would be around £30-40.
If you would like me to recommend a suitable engineer to attend to fit the element, please provide your postcode.
The video here explains how to open a locked washer door, and is generic regarding of make or model.
Should you wish to perform the repair yourself please refer to the video here.
Please let me know if I can be of any further assistance.
I am sorry you do not feel I have been able to answer your question, and will refer the matter to customer services to process your refund.
