Error code IE

The original pcb failed. This part was discontinued, LG gave me the part # for a new pcb. Replaced it, but now times out after 30 seconds of water fill on error code IE. Replaced the inlet valve, but same problem. How does it know when to stop filling? Can't find a float switch. Could the new pcb be incompatible?

A pressure sensitive dome is common on some units. as pressure builds, an air switch is activated.
otherwise there has to be a water contact switch.
the air switch dome can be located near the pump under the unit.
good luck

the drain pump should start and drain all water then start a cycle. Good luck

What is code 67 on a LG PTAC

Hi Jason, The link below is a web page, Click the 4th down for an LG Ductless HVAC & PTAC Error Codes manual.....

Code 67 ODU fan motor not rotating or proving rotation. Verify fan motor plugged in correctly & fan rotates freely. This can be a failed motor, failed board or motor could have failed and caused board failure as well. Verify 310V DC on motor wires separated by empty terminals on plug with motor plugged in, 0V DC = failed PCB, 310V DC = likely failed motor. Next step: Unplug motor and manually spin the fan (keep it spinning): on same wires you just tested, 0V DC indicates motor failed and caused board failure. 14-30V DC indicates a good motor

Error code CH 02. Since this LG model has been discontinued I am looking to repair if possible. Thermistor error but which one and can I just order a new one and simply unplug the old and plug in the new?...

Indoor Pipe Sensor or Outdoor Sensor Assy fault, Open or Short. Disconnect from PCB and measure resistance. Air sensor = 10 kOhm at 25C, Pipe sensor = 5 kOhm
at 25C. If not replace sensor.

Very easy to replace, just make sure power is off and wait 10 mins for capacitors to discharge then swap over thermistor and power up.

I have an lg tromm with an ie code replaced water pump and main board and the ie error still there cleaned inlet filters also help

I have had problems similar to this with my Tromm, and I was able to get it to cooperate by unplugging it for a short period (30 minutes) of time and trying again. This cleared the error code and the washer worked for a long time before having to redo this procedure.

Im getting error code "LE" on my lg dishwasher

While LE is the LG error code for "Motor Error": The Motor is working abnormally, it does not always mean that the motor itself has failed.
As you replaced the pump motor, are you certain that the Impeller of Washing Pump is turning freely? Next, is the Blade spinning freely?
If everything above is obviously not locked, the next item is the controller board. (PCB)
Hope that helps. Please report back with your findings! Good Luck.

Hi, i have 2pcs of canon iR2016 Digital copiers which displays error codes of E246 AND E247. these errors are not in the service manual, please help

Sir i am a Canon trained tech. I just checked our website and my service information. I found the following. I suspect someone has been working on these machines or swapped some parts around.

Page 1 of 2
Digital Copiers, Including All imageRUNNER Products
Information About The New Soft Counter Circuits
This Technical Publication presents information about the new Soft Counter circuit that replaces the mechanical counter
used in the past. There are three (3) PCB’s associated with the new Soft Counter circuit; the Counter Memory PCB,
Main Controller PCB and the Serial Number PCB. A description of their function is provided below. Use this
document as a reference for current and future models that use the Soft Counter circuit.
Counter Memory PCB
On the latest Canon digital copiers, such as the imageRUNNER 5000, imageRUNNER 8500 and imageRUNNER 2200
series, there are no mechanical counters. Instead there is a Counter Memory PCB. This PCB is usually mounted on the
Main Controller PCB with one screw. The Counter Memory PCB is imprinted with the serial number of the machine
the first time power is turned ON and cannot be moved to another machine. Attempting to do so will generate an E246
error code. In the event of a Counter Memory PCB failure, a new one from stock (see Note 4) can be installed into the
machine. At that point the Main Controller PCB will transfer its present total count as indicated in “Counter Check” on
the control panel (recorded the last time power was turned OFF) to the new Counter Memory PCB and the total counter
will increment from that count on. Never attempt to operate a machine without the Counter Memory PCB
This may generate an E245 code, which can only be cleared by “zeroing out” the Main Controller PCB by
one of our A.P.R.F.’s (Authorized Parts Repair Facilities).
Main Controller PCB
The Main Controller PCB, aside from performing other tasks, retains the total count by means of SRAM with a battery
back up after power has been turned OFF. If, however, the Main Controller PCB has been replaced with either a new
one or a used one, it will read in and record the total count from the Counter Memory PCB retained the last time power
was turned OFF. The total count will then increment from that count on.
Note 1:
Even though the total count will be the correct value for that machine after replacing the Main Controller, the soft
counters in Service Mode will not. If a new Main Controller was used for the replacement, then all soft counters in
Service Mode (service counters in “Counter Mode”) will be zero. If, on the other hand, a used Main Controller was
used for this replacement, the soft counters previously recorded on that PCB would be shown. At that point it is
advisable to clear these values in Service Mode using Function>Clear>CNT-MCON.
All Main Controllers sent to our A.P.R.F.’s for repair will be “zeroed out” before being sent back to the dealer.

04-30-02 GT I
Note 2:
The Counter Memory PCB and the Main Controller PCB should never be replaced simultaneously!
This will
generate an E354 code and assistance from the Canon Reseller Technical Support Center Hotline will be required. If
the Main Controller is sent to one of our A.P.R.F.’s for repair, you must remove the Counter Memory PCB
before sending it out!
Failure to do so will only increase down time for your customer.
Note 3:
If the Main Controller PCB is replaced, ensure that connector J1023 is connected. If it is not, an E350 will be
Serial Number PCB
The Serial Number PCB’s main function is to identify the machine’s serial number. This PCB cannot be moved to
another machine.
Attempting to do so will generate an E355 and assistance from the Canon Reseller TechnicalError codes not listed in the Service Manual:
There are various error codes that are not listed in the Service Manual. Canon U.S.A., Inc. reserves the right to treat
these error codes as Proprietary Information. If you encounter any of the following error codes, contact your Canon

E245 E246 E247 E350 E354 E355
Note 4:
Please be advised that Canon U.S.A., Inc. treats the Counter Memory PCB and Serial Number PCB as “restricted” parts.
When a dealer orders these components they will be asked to provide the reason for their replacement, and the original
PCB will have to be returned to Canon U.S.A., Inc. for evaluation.
