A conveyor dish machine stays reliable when the tanks are drained and cleaned every day, the wash and rinse arms are clear, the curtains and conveyor are inspected, and the temperatures and chemicals are logged. Most breakdowns in busy kitchens start as scale, food debris or a worn curtain that nobody noticed. This checklist breaks the work into daily and weekly tasks and shows where a technician is needed.
Why conveyor machines need a routine
Conveyor machines handle high volumes of dishes through multiple tanks, spray zones and a heated final rinse. When one part fails, the whole line backs up. They also run a lot of water and chemicals, so scale and residue build quickly. A routine of short, regular tasks costs far less than a stopped belt in the middle of service.
Daily tasks
- Drain and flush the tanks. Drain at the end of service, remove the scrap trays and strainers and rinse them.
- Clean the wash and rinse arms. Pull the end caps and flush out debris. Check each nozzle for clogs.
- Inspect the curtains. Curtains hold in water and heat. Torn, curled or missing curtains let water and heat escape, so replace them as needed.
- Wipe the interior and door seals. Leave doors open to dry overnight if the maker allows.
- Check chemical containers. Fill detergent, rinse aid and sanitizer as needed.
- Log temperatures. Note the wash and final rinse readings during service.
If the machine uses gas or steam for heating and you smell gas, leave the building and call the gas utility from outside. For electric machines, turn off power at the disconnect before reaching into the machine for any cleaning.
Weekly tasks
Delime and descale
Hard water scale coats heating elements, tank walls, pumps and nozzles. Use the delimer recommended for your machine and follow the instructions. Rinse thoroughly afterward so no chemical remains. Watch for white crust, a sign that scale is returning quickly.
Inspect the conveyor and drive
Check the conveyor rack or belt for tracking. Look for bent pegs, worn links and debris jammed in the track. Listen for new noises. A conveyor that stalls or slips often has a worn drive part or a jam. Check that the chain or belt tension is as the maker states.
Check the pumps and strainers
Weak spray pressure points to clogged strainers, blocked arms or a tired pump. Look at the pump housing for leaks.
Test the chemical feed
Test the sanitizer strength with strips, or verify the final rinse temperature, depending on your machine type. Check the feed tubes for cracks and crystals.
| Task | Frequency | Done by |
|---|---|---|
| Drain, flush, clean strainers | Daily | Staff |
| Clear arms and nozzles | Daily | Staff |
| Inspect curtains | Daily | Staff |
| Log wash and rinse temperatures | Each shift | Staff |
| Delime tanks and heaters | Weekly or as needed | Staff or technician |
| Check conveyor tracking and drive | Weekly | Staff, then technician |
| Test chemical feed and pumps | Weekly | Staff, technician if off |
| Full service and calibration | Every 6 to 12 months | Technician |
Signs it is time for a technician
Call when the conveyor stalls or jerks, the machine will not reach rinse temperature, you see leaks around the tanks or pumps, dishes come out dirty despite clean arms, or a breaker trips. Also call when you see damaged wiring or hear grinding from the drive. Common repairs include drive motors and gear parts, heating elements, thermostats, limit switches, pumps, solenoid valves and control parts. We explain what is worn and what it costs before work.
Document and train
Post the checklist at the machine and initial it daily. Train new staff to inspect curtains and clear arms before starting. A short record of cleaning and temperature readings also helps when the health inspector asks about your sanitizing process, and it helps us understand when a problem began.
We repair rack conveyor and flight-type machines and quote in writing before work begins. Our work carries a 30-day warranty. We are an independent repair company with factory-trained technicians, not affiliated with any maker.
Planning a service visit
Schedule a full service once or twice a year on a day when the kitchen is closed or slow. The technician can check the drive and chain, test the heaters and thermostats, inspect the pumps and seals, calibrate the temperature controls and test the chemical feed rates. Small items that wear slowly, such as bearings, seals and curtain hangers, are easy to replace during a planned visit but cause an unplanned stop when they fail mid-service. Keep a record of what was replaced and when, so the next visit starts from facts.
FAQ
How often should a conveyor dish machine be deliming?
Many kitchens delime weekly, and more often in hard water. Follow the maker schedule and what you see inside the tanks.
Why are the curtains important?
They hold in heat and water and keep spray inside. Missing or damaged curtains waste energy and can cause wet floors.
What causes the conveyor to stop?
Jams, a worn drive part, a failed motor or a tripped safety switch. A technician can find the cause.
Do you service flight-type machines?
Yes. We repair rack conveyor and flight-type machines.
