Safety first: Disconnect power before adjusting internal dosing equipment.

• Verify detergent: Confirm that the correct commercial detergent recommended by Maidaid is being used and that the container is not empty.
• Prime and test dosing pump: Use the priming function to ensure the Maidaid detergent pump delivers product. Check suction and delivery tubes for blockages.
• Increase dosage: Adjust the dosing pump rate slightly and monitor results over several cycles.
• Check wash temperature: Ensure the machine is heating correctly; if not, investigate heater and thermostat faults.
