6. Check if the connectors on both sides of the
communication cable are still connected
Connect the connectors on the electronic timer board
and the inverter.
7. Check if the wiring is still continue Repair the wiring
8. Check if the output relays that activates the
safety inverter contactor is functional
If the relay is broken, replace the wash computer
DIAGNOSTIC CODE D12 : ALARM FREQUENCY INVERTER
Diagnostic Code D12 occurs when the frequency inverter goes into alarm. Except for the THT and the OV3
fault where the timer software will reset the inverter automatically (only 1x). The active process will be
interrupted immediately.
DIAGNOSE(ERR30):
1. Check if the correct machine type is
selected in the Configuration Menu.
If the wrong machine type is selected, enter the right
machine type
2. Check if the correct inverter parameters
have been implemented.
Load the correct Inverter parameters.
3. Check the frequency inverter error list to
know what happened.(See manual inverter)
If the fault is persistent, contact the manufacturer
DIAGNOSTIC CODE D11 – D12 : PWM MOTOR DRIVE ERRORS AND PROBLEMS
D11 (E63, E64, E65) Drum doesn’t turn (no reset drive)
D12 (E66) Extended Speed (no reset drive)
D12 (E67) Continue Spin (no reset drive)
Problem Cause Solving the problem
The motor is spinning at 150 rpm * the belt is broken (when the belt
is broken, the load is so small
that the motor starts spinning at
150 RPM
* Change the motor belt.
The motor is shaking * bad contact in motor or
communication cable
* Check wiring and pin
connectivity and repair the
problem
The drum is not able to spin at it’s
max speed
* 1 phase is missing * Verify if the connector of motor
supply is well connected
The belt is slipping * check if the belt is wet * Make sure that no water gets on
the belt
DIAGNOSTIC CODE D13 : COIN BLOCKING 2
When the input for coin drop 2 is blocked for more then 15 seconds, diagnostic D13 will be displayed.
When the problem disappears, the Diagnostic message will be cleared automatically.
Most likely the coinbox will get filled up completely with coins until they interrupt the infrared signal of the coin
sensor. After removing these coins the coinsystem will work again in a normal way.
DIAGNOSE (ERR17):
1. Check the well functioning of coin drop 1 If the coin drop micro contract or optocoupler is not
functioning 100% : replace the coin drop
2. Check the continuity of the wiring If the wiring is not continuous: repair the wiring
