Shutting down your large warewash machine for the school holidays

As the school term ends, it’s vital to shut down your large warewash machine correctly. Proper cleaning and shutdown help maintain hygiene, prevent mechanical issues, and ensure a smooth restart when staff return after the break. Below are clear step-by-step instructions to help your team shut down the machine safely and efficiently. 

Step-by-Step Summer Shutdown Guide 

1. Drain the Machine Tanks

Before switching off the machine, make sure all tanks are fully drained. Some models feature an Auto Clean function, but manual cleaning is still required—daily at minimum. 

2. Stop the Conveyor and Drain Water

Tap Conveyor OFF. 

Use the Navigation Key to select “All Tanks: Drain Water”, then confirm using the Menu Selection. 

The display will show: “Machine being drained.” 

3. Use the Partial Drain if Needed

A partial drain option is available to empty just the prewash tank. This is particularly useful during busy periods and helps maintain top performance throughout the day. 

4. Remove Internal Components for Cleaning

Once the machine is fully drained, open the inspection doors and remove the curtains, strainer baskets, and flat strainers. 

5. Remove and Clean Wash and Rinse Arms

Carefully remove the upper and lower wash arms, then do the same with the rinse arms. Clean all parts thoroughly by hand to ensure any buildup is removed. 

6. Clean the Machine Interior

Switch the machine OFF and hose down the interior. If any water remains, drain again via the menu. 

7. Focus on Blue-Labelled Parts

All parts marked with blue labels must be cleaned thoroughly. These are typically high-risk areas where residue and bacteria can build up. Cleaning them daily is essential. 

8. Cleaning your Large Warewash equipment

Daily cleaning prevents the build-up of food debris, grease, and limescale, keeping your machine safe, efficient, and ready for the next use. 

Regular maintenance reduces the risk of breakdowns, ensures optimal cleaning performance, and keeps your machine in peak condition for a seamless restart after the holidays. 

Top Tips for Leaving Your Machine Unused  

• Please remove the detergent lines (also known as chemical hoses) from chemical containers and prime through with water. This will help prolong the life of the chemical tubing and stop chemicals crystallising. 

• Isolate the electrical supply, turn off and disconnect the water supply (where possible) to avoid any standing water. 

• Depending on the model, leave the hood up or door open when cleaned out. This will help circulate free air and keep the chamber fresh.
