Part Two: Error Code And Trouble-shooting Strategies for Induction Cooktops
Publish Time: 2018-11-03 Origin: Site
The owner and chefs of Commercial Kitchen Trust chose the Lestov induction cooktop because of its high quality and good service. Below are introductions to error codes and troubleshooting strategies for 380v induction cooktops (Warm tips:
A. If the problem you may experience is easy to fix, that is very nice. But again, if you need special help, please email us or call us;
B. At any time, welcome your engineers or technicians to visit us and learn more skills of induction cookers.)
Error code: E6
--Possible reasons for the error: Overheat protection for the bottom of the pot
--Trigger condition of Error & Trouble-shooting strategies:
Trigger condition of Error | Trouble-shooting strategies |
Probe of pot bottom short circuit, the disoperation switch broken, Water shortage alarm board broken | Check whether the pot bottom probe is short-circuited, whether the switch is damaged, and whether the water shortage alarm board is damaged. |
Error code: E7
--Possible reasons for the error: NTC failure for the bottom of the pot
--Trigger condition of Error & Trouble-shooting strategies:
Trigger condition of error | Troubleshooting strategies |
Probe of the pot bottom open circuit. | Check if the bottom probe is open circuit. |
Error code: E8
--Possible reasons for the error: Low voltage protection
--Trigger condition of Error & Trouble-shooting strategies:
Trigger condition of Error | Trouble-shooting strategies |
Low pressure alarm protection | Control panel sampling circuit is abnormal; check whether the power voltage is lower than 304V. |
Three-phase alternating-current supply loses 1 or 2 phases | Use a magnetic table tool to check whether the power terminal is AC 380V. If the measurement is AC 200V at one time, the power is short of phase. (Measure AB, AC, BC separately.) |
Power supply overloaded | Use an undercurrent meter to measure the current; check if there is "intermittent heating" when the gear is not working. |
Drive wire inserted reversely | Check whether CN1 and CN2 on the control board correspond with CN1 and CN2 on the resistance board. |
Resistance plate broken | Check the small components on the resistance plate for obvious shedding and damage, or measure the resistance plate 4-5, 6-7 with a Magnetic table tool for breakdown or conduction. |
Control panel broken | Check the small components on the control board for obvious shedding and damage; if not, change the control board to distinguish whether it is good or bad. |
High-pressure sampling wire on control board and resistance board is off or dis-welded | Check whether the high-voltage sampling wire on the control board and resistance board falls off; reinsert it and weld well if so. |
Cooling fan broken | Check whether the cooling fan is working normally. Use a magnetic table tool to measure the resistance of the fans; the AC fan has resistance while the DC fan has no resistance. |
Pot material does not match, IC does not match | Use the magnet to test if the pot material is magnetic, or replace the IC for testing. |
Error code: E9
--Possible reasons of Error: High voltage protection
--Trigger condition of Error & Trouble-shooting strategies:
Trigger condition of Error | Trouble-shooting strategies |
High - voltage alarm protection, there is water leakage to the coil or coil terminals are short circuited | Control board sampling circuit is abnormal, check whether the power voltage is higher than 456V, whether the coil is inflow of water, and whether the coil terminal are short circuited. |
Error code: Ed
--Possible reasons of Error: Undetected switch
--Trigger condition of Error & Trouble-shooting strategies:
Trigger condition of Error | Trouble-shooting strategies |
Switch broken or wire disconnected | Check whether the switch or switch wire is broken. If it is not, change the switch to test it is broken or not. |
