2 Errors and Troubleshooting
E5 Dishwashers are electronically controlled and some faulty conditions can be detected by the
electronics. These errors are detected 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.

if the same fault occurs duringthe functional test again.At the end of the test diagnossed errors date
will also be cleared.
2.1 Error codes
Errors diagnosed during the dishwasher usage will be displayed on screen;
• [E:01] and [E:02] will be displayed also in normal use.
• Other error codes will be displayed only in service mode.
Overflow
No water
Heater fault
Turbitiy fault
Position error Valve Spray arm control
NTC fault
Water inlet valve fault
Heating pump (BLDC motor) Dry running error

2.2 Troubleshooting
2.2.1 Overflow [Er:01]
If the control system senses an overflow signal, this error will occurs.
Control unit drains the water inside and checks the signal;
• If there is no overflow signal, dishwasher will continue to work normally.
• If the overflowsignal remains, the system stops responding to any user input except the ON/OFF
button and waits for the service.
Possible reasons:
• Broken components or torned hoses
• Malfunction of drain pump
• Malfunction of flowmeter
• Malfunction of water inlet valve
• Cable harness errors
• Faulty electronics
2.2.2 No water [Er:02]
Incoming water to the machine is monitored via a water counter (flow meter) system. During the
“Water Inlet” step if no pulses could be sensed by the electronics, No Water condition occurs.
At this condition the dishwasher will wait until water signal is detected. If necessary water signal is
detected the machine will continue its normal operation.
Possible reasons:
a. Malfunction of water inlet valve
b. No water
c. Insufficient water pressure
d. Cable harness errors
e. Faulty electronics

2.2.3 Heater fault [Er:03]
The water temperature in the machine is measured by an NTC (negative temperature coefficient).
At heating steps, if the temperature rise is less than 1 °C within 3 minutes heating fault occurs.
When the fault detected software skips the heating step and continues the program
with the next step.
Possible reasons:
a. Malfunction of heater
b. Malfunction of NTC (constant NTC resistance)
c. Cable harness errors
e. Faulty electronics
Note: During the first 3 minutes of a heating step the water temperature is not controlled. The
control system waits so that the temperature inside the machine reaches balance.
2.2.4 Turbitiy fault [Er:04]
Turbidity sensor is the component that measures the amount of dirt in the water. The machine
uses this data for the steps of Auto Program (if applicable). If the proper data from the turbidity
sensor cannot be received, Turbidity Sensor Error occurs.
When the error occurs, the software continues the program as heavy dirt level.
Possible reasons:
a. Malfunction of Turbidity Sensor
b. Cable harness errors
c. Faulty electronics
2.2.5 Position error Valve Spray arm control [Er:05]
The spray arm valve is the component that diverts the water flow between the upper and lower
trays. Position of the valve is checked by the main board. The position error occurs if the proper
position signal could not be received from the valve.
When the error occurs, the electronics drives the valve until proper position signal is achieved.
Possible reasons:
a. Malfunction of spray arm control valve
b. Cable harness errors
c. Faulty electronics

2.2.6 NTC fault [Er:06]
At the heating step, if NTC resistance is measured beyond the specified resistance values or if the
NTC resistance is measured as open/short circuit NTC fault occurs.
When the fault is detected software skips the heating step and continues the program with the
next step.
Possible reasons:
a. Malfunction of NTC
b. Cable harness errors
c. Faulty electronics
2.2.7 Water Inlet Valve Fault [Er:07]
Main board monitors water counter pulses at every step of the washing program.
If pulses are received from the counter at any step other than Water-Inlet; Water Inlet Error occurs.
When the fault is detected software drains the water inside the dishwasher.
Possible reasons:
a. Malfunction of water inlet valve (stuck as open)
b. Faulty electronics
2.2.8 Heating pump (BLDC motor) Dry running error [Er:13]
The heating pump (BLDC motor) checks the amount of water. If the flow rate decreases a dry run-
ning error occurs.
Possible reasons:
a. Malfunction of water inlet valve (less water in dishwasher)
b. Dirty filter or spray arm
c. Faulty connection between motor and electronics
