The ice dispenser is overflowing or leaking - how to unclog the drain?

Question

Accepted Answer

The water overflow at the dispenser may be due to a clogged or improperly configured drain. According to the SPA160 manual, here’s how to diagnose and resolve the issue:

Check the drain and plumbing

Minimum diameter of the drainage pipe: The manual states a pipe of 12.7 mm (1/2") minimum. Check that your pipe is not smaller.
Physical inspection: Ensure that the drainage pipe is not bent, crushed, or blocked by debris or limescale.
Drain ventilation: The manual recommends a separate ventilation for the drain to prevent algae buildup. Make sure the drainage pipe is not closed at its end.

Check the level and position

The basin must remain perfectly level for proper operation. Use a level to check the horizontal alignment of the machine.
Ensure that the floor siphon for the dispenser is in place and accessible.

Maintenance of the circuit

Perform a monthly cleaning of the water circuit with the recommended solution: 100 ml of Manitowoc cleaner + 4 liters of water, followed by a rinse with clear water. This can remove deposits that hinder drainage.

If after these checks the overflow persists, the manual recommends contacting an authorized technical service via www.manitowocice.com or the Manitowoc distributor at 920-682-0161. The problem may originate from the internal distribution system.
