Menu line which should show actual weight not displayed.
Possible causes :
The option “DISPLAY WEIGHT ALLOWED” may be switched off (have the answer “No” along- side) in “Settings 1”. Possible fault in communication with CPU board or display. The fault can also be in the scale unit.
Fault-fi nding procedure :
•Check in "Settings 1" that the option "DISPLAY WEIGHT ALLOWED" has "Yes" alongside.
•Check that the cables/wiring for CPU communication and power supply are connected to the scale unit and in good condition.
•If the washer extractor appears to be working normally apart from the absence of weight parameter display, try replacing the scale unit as described under "To replace the scale unit".
If you suspect that the weighing equipment is not displaying accurate weight value.
Probable cause :
Probably a faulty load cell.
Fault-fi nding procedure :
•Place an object of known weight at one corner on top of the washer extractor. Check the weight shown on the display. Move the weight to each of the other corners of the machine in turn, checking the display each time. If one corner is different from the others, this will reveal which load cell is faulty.
•Check that the load cell in question is mechanically unobstructed, free of anything which could affect its normal functioning.
•Replace the load cell as described under "To replace a load cell".
