Question 1

Why is water leaking under my IM65NEHC ice maker and how can I fix it?

Accepted Answer

Water leaks under the IM65NEHC ice maker can have several causes. Here are the checks to perform:

Check the positioning of the drainage pipe

According to the specifications in the manual, the drainage pipe must be positioned with its outlet at least 5 cm above the opening of the drainage pipe on the floor. If the drain is not properly elevated, water will back up and leak under the machine. Ensure that the drainage pipe is sloped downwards and that its outlet does not dip into the drainage pipe.

Check the water supply pressure

The water pressure should be between 0.07 MPa (0.7 bar) minimum and 0.8 MPa (8 bar) maximum. Excessively high pressure can cause leaks at the connections. If your installation exceeds 8 bar, install a pressure reducer.

Inspect the connections and seals

Check the condition of the water inlet connections and seals (threading and sealant). A leak in the machine's piping may indicate a worn seal or a loose connection. In this case, a qualified technician should intervene.

Check the water quality

If the water is hard or contaminated, mineral deposits can damage the internal seals. The manual recommends installing an external filter or a water softener in case of hard water.

If the leak persists after these checks, contact a qualified Hoshizaki maintenance technician.
