Troubleshooting Procedures
E8 Dishwashers are electronically controlled and some faulty conditions can be detected by the electronics. These errors are detect-
ed not only in the functional test program but also during the washing cycles. The previously detected errors are kept in memory and
shown in display.
When the test programs are started, the error data in memory will be cleared which enables the technician the ability to determine if the
same fault occurs during the functional test again. At the exit of the test diagnosed error data will also be cleared.
If the control system senses an overow signal for 20 seconds from the overow switch the system enters a standby state for 2 min-
utes. During the standby time the drain pump automatically runs. After the standby duration is completed if the control system still sens-
es an overow signal the machine stops responding to any user input except the ON/OFF button.
If there is no overow signal after 2 minute standby time the machine continue to work normally.
Overow Er: 01
Possible reasons:
• Broken components or torn / split hoses
• Malfunction of drain pump
• Malfunction of ow meter
• Malfunction of water inlet valve
• Cable harness errors
• Faulty electronics
