White, Grey Deposits Inside the Glasswasher

Cause

• The water in the wash or rinse tanks is too hard.
• Hard water salts may have been deposited resulting in poor heat transfer to wash/rinse solutions. This will cause the washer to operate under temperature and there will be a rise in energy costs.
• Insufficient detergent is being used.
• Inferior detergent formulation is not coping with the water hardness.

What to do

• De-scale machine interior.
• Fit an external water softener or where one is already installed, check it is working correctly.
• Check the detergent bottle is not empty and that there are no kinks or air bubbles in the tubes.
• Call an engineer to check the dosing levels are set correctly.
