6E indicates an ambient sensor error. I would recommend starting by replacing that sensor.

The error code you are getting indicates that the unit is in demo mode. To cancel this press the 2 upper left keys simultaneously for 5 seconds.

Hello
The thermistors can not be calibrated. They are factory set. You will need to replaced them.

The error code you are getting indicates that you have an issue with communication between the main PCB and display PCB.

It seems that you may be getting a door locking error. C-d1 I would start by checking thw door lock switch, door latch motor, or the door latch mechanism.

The C21 code you are seeing indicates that the oven is overheating.

Hi. The E represents an error code. It should be followed by a number or letter. I have attached the service manual for you. This will have all the information on this unit. Error codes start on page 63. We will need to determine what the error code is.

See the link below for the WTA3500 series Bosch training manual. This manual will show disassembly and diagnostics. You will need to disassemble so you can pinpoint where the burning smell is coming from.

Hello
See wiring diagram link below along with all ice maker diagnostics. Yes, the ERC does wire through the water inlet valve and ice maker. Have you manually harvested the ice maker ? If not go to test #44 on the technician sheet link below. This will test the ice maker and the water fill pressure and fill time.

Hello
The 4E error code corrections.
When the filling continues for more than 40 minutes or there is no change of water level for 6minutes.
① Hose Kinked or Check the water Supply Hose(Flood Safety hose is not supported)
② Water Valve Defect (Check resistance approximately 1K~2KΩ) or filter blockage
③ Wire Harness connection problem
④ Main PBA (Check for AC 120V)
⑤ Hose Pressure Hole

Causes
* Water supply valve fault
* Main PCB fault
* Water supply hose might be bent or use flood safe

Step 1
* If the water supply valve has a wire disconnected, reconnect the wire.
* Check whether the water supply valve is clogged with foreign material and whether water is supplied continually.
* Check whether no water is supplied because of freezing in the winter season.
* If the PBA relay operates abnormally, replace the PBA.
* Check the resistance for the water supply valve. Resistance: 1.0 to 2.0 kΩ between the terminals of the water supply valve.
* Check whether there is foreign material in the water valve filter.
* If the water supply valve filter is clogged, clean filter.
* Check the inlet filters dirty or clogged.

We have the service training manual on your model only. See the link below , hope this can help.

Hello
See the exact service manual for the WM38 series LG unit. Also see the link to the WM34 video series unit we have in the link below. We currently do not have the WM38 series videos. Hope this can help

Hello
See the service bulletin links below. also see tech. sheet.

Hello
See the service manual link for your model below. The top panel parts breakdown is on page #50 in section 7-1. Hope this helps.

Hi. It looks like there is only one inlet valve on the back for this unit. I have attached the service manual for you. You could have a frozen water line or tank to the dispenser or the filter could not be engaged or a faulty filter housing.

That is a strange one. It is going off balance? are the shocks bad? Does it drain out properly? It should be throwing error error code. That makes it tough with out an error. does it do this with no clothes as well? Do you let it go through the whole spin cycle? it will get to high speed with only a few mins left.

d5 indicates an open door error. Check Door is properly closed, Check if there is a deformation of the door hook ,Fault of Reed S/W which is detecting if door is open or close ,Go to “Quick Test Mode” and then do Door lock/Unlock Test and Motor Test.

Hi. Sounds like you covered everything that would normally cause a frozen fill tube. I did not find any service pointers for this one. I know they had issues with poor insulation on these units. The main issue would be ice forming on the outside of the unit. This would be on the back of the unit. They had “blanket kits” for this. Check the back of this unit for that ice. Look for rust spots or condensation. The ice would form around water lines in the back. This could be why your fill tube is keeps freezing. Also, there is an update for the seals in the ice box. the issue would be frost and ice forming in the ice box around the ice maker.

E27 indicates a temperature sensor error.

dl is a door open error. Check Door is properly closed Check if there is a deformation of the door hook Fault of Reed S/W which is detecting if door is open or close Go to “Quick Test Mode” and then do Door lock/Unlock Test and Motor Test.
