What does diagnostic code lf mean - Amana PTC153B35AJ Air Conditioner

Lf = long fill. Make sure screens in hoses and water valve are clear of debris. Also be sure hot and cold water hoses aren’t reversed.

LF means Long Fill. Here is a video showing you how to fix that code: https://www.youtube.com/watch?v=1M-XgRT3obc I hope that helps! :)

Dos your machine sometimes continue to fill Fl could be LF I have seen the codes pop up different than the tech sheet anyway LF is a long fill wish I could tell you the exact location of the service manual WP always moves it try on the inside of the bottom panel first if not there look inside might be mounted on wall a few times located under top panel read it it will explain how to place machine into diagnostic usually on LF the unit is draining slow or the black hose that leads to the pressure switch has popped loose a rubbed against basket pulley causing a small hole in the rubber this will give a LF error hope this helps

Hi Sherry,

The code definition for LF is a LONG Fill (F30). What does that mean is the next question? Here goes.

a. The fill hose may have a pinch or fold between the connections on the pressure in .
b. Are the hose screens plugged at the connections.
c. Is the water siphoning out of the drain hose ?
d. Is the water pressure at peak, check valve, filters before washer.

Now if your savvy hungry. Here is a learning curve link

Okay. The next link is for the manual for your favorite machine. Manuals and Troubleshooting Whirlpool Whirlpool Cabrio Washer Fault Codes . I tried this and you need registration.


I decided to go one step further and track down a printable and savable resource for you. Yes, all, the fault codes and what they mean.

Whirlpool Cabrio Washer Fault Codes

I did pretty good from memory but that link leads you to a printout you can keep right by your washer. Most of the occurrences are easy to fix without a technician. Hope this makes your day. Better. Fare. Well.

• B0041

CIRCUIT DESCRIPTION
The inflatable restraint side impact module-LF deployment loop consists of the inflatable restraint side impact module-LF, the inflatable restraint side impact module wiring harness, and the side impact module-LF high and low circuits. A shorting bar used within the side impact module-LF connector shorts together the side impact module-LF high and low circuits when the connector is disconnected. This helps to prevent unwanted deployment of the inflator module during servicing. During a side or frontal crash of sufficient force the inflatable restraint Sensing and Diagnostic Module (SDM) allows current to flow through the deployment loop in order to deploy the side impact module-LF. When the ignition is turned ON, the SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a Diagnostic Trouble Code (DTC) will be stored in memory.

CONDITIONS FOR RUNNING THE DTC
Ignition 1 voltage is within the normal operating voltage range.

CONDITIONS FOR SETTING THE DTC

• DTC B0040 will set when the side impact module-LF deployment loop resistance is less than 1.3 ohms for 500 milliseconds .
• DTC B0041 will set when one of the following conditions occurs:
• Side impact module-LF high circuit is less than 2.4 volts and the side impact module-LF deployment loop is more than 6 ohms for 500 milliseconds .
• Side impact module-LF deployment loop resistance is more than 4.8 ohms for 500 milliseconds .
• DTC B0045 will set when one of the following conditions occur:
• Side impact module-LF high and/or low circuits is short to ground or short to voltage for 500 milliseconds .
• Side impact module-LF high circuit is less than 2.4 volts and side impact module-LF deployment loop resistance is less than 6 ohms for 500 milliseconds .

ACTION TAKEN WHEN THE DTC SETS
The SDM commands the AIR BAG indicator ON via Class 2 serial data.

CONDITIONS FOR CLEARING THE DTC

• The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
• A history DTC will clear once 255 malfunction free ignition cycles have occurred.

DIAGNOSTIC AIDS
The following are possible causes of the malfunction:

• A short between the side impact module-LF high and low circuits
• An open or a high resistance in the side impact module-LF high or low circuits
• A short to ground or a short to voltage in the side impact module-LF high or low circuits
• The side impact module-LF connector
• The SDM connector
• A malfunctioning side impact module-LF
• A malfunctioning SDM

LF (F30)
LF flashes when the control don't sense any water coming in like it is supposed to do. Things to check:
Hoses connected; water turned wide open.
Hose screens plugged.
Is water siphoning out due to having the drain hose too low? (30 inches above the floor)
Pressure hose from tub to control loose, pinched, hole, Sediment in tub? Blow that tubing out and re-secure; retry with water OUT of tub so the pressure can properly build in that tubing.

hello

mean while LF error code indicates that the water temperature sensor reading is out of range (below 23 degrees F or above 217 degrees F).

The LF error code is an indication of a water temperature sensor error. There is a chance that there is a loose wire connection on the water temperature


however,what you need to do tp fix up the problem is to unscrew the washer then clean up all forms of dry and water you can seen in it with this the problem of the LF error code is solve .

please make sure that all form of power supply is put OFF before you can do this

thank you and thanks for using fixya.

lf code means long fill. If the water fill time exceeds 10 minutes, the water valves are turned off and lf is flashed. Press STOP/CANCEL to clear the display.

See the following Whirlpool Service Manual for their Cabrio washer which is basically the same as the Kenmore Oasis.

(Saved Code) EXPLANATION AND RECOMMENDED PROCEDURE
(F30)
Long Fill
LF flashes when the water level does not change for a period of time after the valves are turned on OR water has disengaged
the basket but control does not detect a water level change.
• Is water supply connected and turned on?
• Are hose screens plugged?
• Is water entering the tub? If so check pressure hose connection to machine/motor control.
• See TEST #2.

Have same problem. Service tech said LF code is caused by low water pressure coming into machine. Tech verified water flow looked fine, getting new controller installed tomorrow.
