E17 displayed; machine indicates low incoming water pressure or insufficient flow.

Safety first: Turn off power before moving the machine or disconnecting hoses.

• Check stopcock and isolation valves: Ensure all valves feeding the Classeq dishwasher are fully open.
• Inspect inlet hose: Look for kinks, crushing, or sharp bends in the water inlet hose. Straighten or replace as needed.
• Clean inlet filter: Turn off water, disconnect the hose at the machine, and remove the mesh filter. Clean thoroughly and refit.
• Measure water pressure: If possible, measure static and dynamic pressure at the supply. If below Classeq's minimum specification, consult a plumber to improve supply (e.g., larger pipework or booster pump).
