How to Fix / Troubleshooting
Safety first: Disconnect power and allow the machine to cool. Use appropriate PPE when handling descaling chemicals.
- Descale the machine: Follow Insinger’s recommended descaling procedure using an approved deliming agent. Circulate the solution through the tank and spray system for the specified time.
- Clean components: Remove wash and rinse arms, strainers, and scrap screens. Soak in descaler and scrub off heavy deposits.
- Inspect heaters: Check tank and booster heaters for heavy scale. Severe buildup may require element replacement.
- Address water hardness: Install or service a water softener to reduce future scale formation.
