Troubleshooting Guide

When receiving the rice cooker requiring repair, please ask the customer about the malfunctions (phenomena), and if necessary, you should also check the inner pot and spill-proof moisturizing cap. Power off first before checking the related components. Check the main unit according to the troubleshooting table below.

Troubleshooting Table
Note: Mark O means the components that may malfunction.

Test Method

Pre-test setting
Make sure that the inner pan set in the cooker and the power cord plugged into the wall socket.

Bubble test

1. Insert the pan into the cooker’s main body, and then turn it slightly clockwise and anti-clockwise to place the pan properly on top of the cast heater.
2. Pour a small quantity of water into the pan so that the bottom of the pan is immersed with water. Close the lid completely and press the switch to start cooking.
3. When the water boils, the cooker will blow off steam. When you see the steam, open the lid, and press the brim of the pan to completely touch the bottom of the pan to the cast heater. Check the water bubbling condition.

See the right figures:

• Water bubbles appear at three areas and are distributed evenly around the circle ————- Acceptable
• Water bubbles appear are distributed unevenly and not around the circle ———————- Unacceptable
• The unacceptable result is possibly due to incomplete contact of bottom of pan and the cast heater. So, please check the heater surface for foreign material and remove them or replace the defective part (pan or cast heater).

Steaming Test
After that, place two or three sheets of tissue paper (gauze) into the pan in such a way that the sheets are spread over the bottom of the pan, then leave the cooker on without closing the lid.

1. Be sure to fully open the lid to protect the plastic parts from thermal distortion caused by steam.
2. Make holes in the tissue paper (or gauze), as shown, so that it will not float up during steaming.

If the unit fails the switching timing test, check for poor contact between the inner pan and the pan sensor. If necessary, remove any dirt deposit from between them, or replace the inner pan and/or the pan sensor.

Keep Warm Test

1. Place a mercury thermometer between urethane foam blocks. (Urethane foam blocks (ASN-300) and the thermometer (ASN- 150H) are supplied as spare parts.)
2. Place the urethane foam blocks holding the thermometer in the center of the bottom of the pan, and allow the cooker to run in the Keep Warm process.
3. More than one hour later, open the lid and read the temperature within 10 seconds.
   • If it is within 65°C ~ 78°C, then considered as normal.
   • If the waring temperature is out of this range, check wether there is any dirt of foreign material stuck on the pan sensor or bottom of the pan, if so, please remove them.

Disassembly and Assembly Instructions

Replacing the switch assembly.

Remove the base.

• Place a rubber pad or similar thing under the rice cooker to prevent damage, and open the lid of the rice cooker, and place the bottom of the rice cooker upward, as shown in the diagram right.
• Pull out the power cord.
• Remove the fixing screws of the underframe (on the side) and those at the bottom (on the underside).
• As shown in the diagram, gently pry at the slot of the underframe edge with a slotted screwdriver, to remove the base.
• Disassemble the wires of the power socket.

Note:

• Do not remove the base by tapping it with a screwdriver, otherwise the screwdriver contacted parts will be damaged. You must use the above method.
• Upon pulling out connectors and similar things, just directly pull them outwards. Pulling them out in different directions will impose pressure on the components connected to them, to cause damages to the components.
• Upon pulling out the fastening terminals at the chuck, please press them down in the direction of the arrow, while pulling the lock catch outward. Press them down in the direction indicated by the arrow, otherwise you will not be able to pull out the terminals.

Disconnect the temperature limiter from the connecting rod.

• Gently bend the sheet at the end of the temperature limiter as shown in the diagram, and fold it into the slot shape at the junction of the connecting rod.
• Separate the temperature limiter from the connecting rod slot.

Remove the bracket

• Remove the wiring on the switch assembly.
• Remove the fixing screws (2 pcs) for the connecting rod bracket.
• Push the bracket towards the temperature limiter, to remove the bracket.

Remove the switch assembly

• Remove the fixing screws of the control baseplate.
• Push the control baseplate upward along the body assembly, to remove the switch assembly.

Assembly the switch assembly.

• Conduct assembly after control switch assembly replacement as per the disassembly steps in a reversed way.
  Note:
• For wiring, refer to Schematic Diagram on P. 4.
