Page 15: Troubleshooting Section
Service Manual Dishwasher LP8 850 Troubleshooting section Some errors can be shown in the display depending on the fail. - E1 Water filling exceeds the preset time. The inlet valve has been opened for more than 4 minutes and the amount of water measured by the flow meter is incorrect. - Page 16 Service Manual Dishwasher LP8 850 - E6 NTC sensor with open circuit. This error is detected by the PCB in the test program procedure. With this error the drain pump will run till the flowmeter keeps stopped during 2 minutes. After that the dishwasher will stop and the buzzer will beep during 30 seconds while the error is shown on display.
