TXF
Case 5:
Replace the pump, if required.
Heater Not Working
Reasons:
1.
Power supply not reached to the heater.
Remedial Actions:
Case 1:
Check the voltage (220 VAC) in heater wires at terminal block. If the Voltage not found, check the
following:
•
Relays (Voltage and Current relay) input and output
•
MCB connectivity
•
Check ON/OFF Switch for wire and terminal connectivity
Further, if the Voltage connectivity is OK, move to
Case 2
.
Case 2:
Remove heater wires from terminal and check the continuity between two heater
’s
wires.
Additionally, also check the continuity between wires and body.
Washing Tub Not Engaging Properly
Reasons:
1.
Sensor position is disturbed
2.
Actuator not working
3.
Washing tub fuse blown
4.
No output from transformer/rectifier
5.
PLC connection is loose or faulty
6.
Relay or relay connection is faulty
Remedial Actions:
Case 1:
Correct the sensor position by moving the tub up or down.
Case 2:
Check 24 VDC near the actuator connector and also check the loose connection, if any.
Case 3:
Check actuator fuse and replace it, if required.
Case 4
: Check the transformer output (must be at 24 VAC) and rectifier output (must be at 24 VDC).
Case 5:
Check PLC connection.
Case 6:
Check input and output power at relay and relay connection.
