Hi, my name is ***** ***** I have been in the home improvement and repair field for 20 years. I will be very glad to help you today.
Is the space needing to be filled at the top? Do you have the dishwasher face that matches the cabinets or is it the stainless finish?
Good morning, further to our conversation the brown plastic strips can be purchased from Bosch Spares here, for £20.84.
I should also mention the part number is ***** and though other firms also sell the strip they actaully work out more expensive, I have checked the following sites
http://www.spares4appliances.co.uk = £22
http://www.ransomspares.co.uk = £24
Please also note the E-NR for your appliance was wrong it is: SMI50C16GB
These will need to be ordered via the website, unfortunately I cant order them on your behalf.
