1. General description
This document includes some technical documentation of the related models
(diagrams, features for the mainly components…), how the error codes are displayed
and their meaning and also the procedure to enter the auto-test with a complete
description of their phases.
There are three different types of appliances:
- TKD 1270 –TKD 1280 –TKD 1480: washing machine with standard motor.
- TKD 1490: washing machine with “inverter” motor and brushes, improving efficiency
and durability.
- TKD 1610 WD: washer-dryer with “inverter” motor, without brushes decreasing the
noise in the motor.

3. Service Test.
There are two possibilities to run the service test: Manual check up component by
component or running the automatic sequence.
Once entering the service menu (see related page depending on the model), we can
find all available options, which are defined below:
↓[K1]
PCB configuration
- Pressing [K8], display will show “xx”, where “xx” is the existing configuration
code.
- Pressing [K2], you can modify the version.
- Pressing [K3], version is modified in the display.
- Pressing and holding [K2] for 3 seconds, changes will be saved.
- Pressing [K8], we will exit this point and display will show “t01”.
↑[K2]
↓[K1]
Stored errors
- Pressing [K8], display will show “Err”and pressing once more [K8], it will show
“Exx”, where “xx” is the error code.
- With keys [K2] and [K3], we move into the stored error list. We have access to
the last 10 errors registered by the PCB, taking into account that each error will
be stored only once (although more than once has occurred).
- If there are not any errors, display will show E00.
- To delete the stored errors, you must press simultaneously [K5] and [K6] for 3
seconds. A beep will be heard confirming the action.
- Pressing [K8] we will exit this point and display will show “t02”.
↑[K2]
↓[K1]

pulsation, water will be loaded until safety level condition. At this time, drain
pump is activated until the tank is emptied
Pressure switch values:
- Empty tank ≈ 600
- Wash level ≈ 400
- Overlevel ≈ 100
↑[K2]
↓[K1]
Temperature sensor and heating process
- Pressing [K8], display will show “HEA”.
- Pressing once more [K8], inlet valve is activated until reaching the washing
level. Heating element is also activated for 5 minutes, display will show the
temperature that the sensor is measuring.
- Pressing [K8], it turns back to the service menu
↑[K2]
↓[K1]
Inlet valve
- Pressing [K8], display will show “UU”.
- Pressing once more [K8], display will show “U1” and pre-wash valve will be
activated for 3 seconds.
- Pressing [K1], display will show “U2” and main valve will be activated for 3
seconds
- Pressing once more[K1], display will show “U12” and both valves will be
activated for a few seconds. Then, only the main valve will be activated and
after this, both of them will be activated until reach the washing level. Then, the
drain pump is activated.
- Pressing [K8], it turns back to the service menu
↑[K2]
↓[K1]
Motor turning
- Pressing [K8], display will show “tUB”.
- Pressing [K8] motor turns anticlockwise sense at 45 rpm for 15 seconds, stops
for 10 seconds and starts to turn clockwise sense for 15 seconds. This sequence
is repeated indefinitely.
- Pressing [K8], it turns back to the service menu

Autotest (see section 4)
- Pressing [K8], display will show “LSt”. Pressing once more [K8], a complete
auto-test is running. It tests the display, load water for both valves, heating
process, drain pump and spin motor (low speed and spin cycle). For the washer-
dryer, this test also checks the dryer components (fan, heating element…)
