Extended Non-Use of Winterhalter Machines

We are well aware of the effect the COVID-19 outbreak is having on our industry.  If you are in a position and it is safe to do so; there are some key measures you should be taking to protect your warewashing equipment. These measures will prolong the on-going life of the machine but ensure it is safe to use again in the future.

Undercounter products

• Drain down using the auto clean cycle procedure. The machine will automatically turn itself off.
• Remove the two wash fields or arms, filter cylinder and wash tank cover – rinse them, ensure they are clean and remove any debris.  Set them aside to drain and dry.
• Wipe out the interior of the machine with a clean cloth and leave the door open for as long as it takes to fully dry.
• The wash fields and filters etc should be re-fitted.
• Close the door to minimise possible ingress from dust, insects etc.
• Turn off the water and electrical supplies

Excellence i & i plus Undercounter (with internal RO pure water unit)

• Follow the same procedure as for undercounter products. 
• However, the RO membranes must be kept moist. This is achieved by periodically flushing them with water to waste.
• It is therefore essential that both the water and electrical supplies to the machine remain on.
• If this is not possible then the RO membranes will need to be conserved by a Winterhalter technician.

Passthrough (hood type) products

• Drain down using the auto clean cycle procedure. The machine will automatically turn itself off.
• Remove the two wash fields or arms, filter cylinder and wash tank cover – rinse them, ensure they are clean and remove any debris.  Set them aside to drain and dry.
• Wipe out the interior of the machine with a clean cloth and leave the door open for as long as it takes to fully dry.
• The wash fields and filters etc should be re-fitted.
• Close the hood to minimise possible ingress from dust, insects etc.
• Turn off the water and electrical supplies

Pot, Tin and Utensil Washer products
