Dishwasher displays E13 and may not start; often linked to low incoming water pressure or supply issues.

Safety first: Turn off power and water before disconnecting hoses.

• Verify building pressure: Open a nearby tap and confirm strong flow. If weak, the issue is external to the dishwasher.
• Check isolation valve: Ensure the small valve feeding the Maidaid dishwasher is fully open.
• Clean inlet filter: Remove the inlet hose from the rear of the machine and clean the mesh filter in the Maidaid inlet valve.
• Inspect hose: Check for kinks or crushing along the entire length of the inlet hose. Replace if damaged.
• Test fill time: Restore power and water, start a cycle, and time how long it takes to reach normal level. If still slow and E13 returns, the inlet valve or pressure switch may need replacement by a technician.
