    the automatically generated solutions are silly. the door closes fine. it fails to run a cycle, and stops early with a CLEAN led lit. The CLEAN led in programming test mode, indicates door switch error...

i would check to see if you are using the factory drain hose or if you have extended the hose to reach the sink drain.
the only other thing that might cause this would be a restriction in the hose at the drain pump outlet, but check the drain hose first.

SOURCE: Can't close Bosch Dishwasher door

I had same problem and was alarmed at the idea of taking the door apart, so I tried the 2 screwdriver option described below - it works!

Open door and get two small screwdirvers behind each side of the catch inside the top of the door and gently apply pressure. The catch should reset itself on 'open' and allow you to shut the door again.

Thanks to all for their postings and helpful advice!

you have to make sure the water temp going into the machine is correct. let the water run for about 2-3mins then start the machine.

SOURCE: latch is not working properly

It's possible the machine is slightly twisted.
Try re-levelling it to start.
You can usually tell when the door is not quite closed if it looks out-of-centre.

The next thing to check is lubrication of the catch. Try some WD-40 in the latch mechanism.

If still no better, then the latch may need adjusting by removing the front panel (unplug machine before doing this).
Grease the moving parts and adjust catch for easy closing.

Just placing a fiberglass batt over the cabinet exterior will quiet it down considerably. Use some thin synthetic cord to tie it in place so that it doesn't crawl off from vibration. If still noisy, remove the door interior panel and check for any insulation there. If there is any appreciable gap at the sides or top, you may need to staple insulation around the interior of the cabinet opening. I'm surprised that they were that lax in noise suppression. Hope this helps!

Camshaft positon sensor 2001 toyota mr2 how to bench test


Most cam and crank sensors are magnetic or hall effect switches. Usually, if you set your multimeter to ohms or continuity, it should go from open to zero when you pass metal between the posts on hall effect or a magnet on magnetic switches.

I have a Saturn 2001 4door s series the security light is on and won't start what can I do


Passlock
The passlock system is a vehicle theft deterrent system which deters drive-away vehicle theft by disabling engine operation if the ignition lock cylinder is not rotated with the proper mechanically cut key.
The passlock system is made up of an ignition switch assembly, passlock sensor, body control module (BCM), instrument panel cluster (IPC), and a powertrain control module (PCM).
The ignition switch contains a magnet mounted on the lock cylinder and a passlock sensor assembly which consists of security hall effect sensor, tamper hall effect sensor, and output resistors. A drill proof metal shield is also staked over the sensor housing.
The passlock sensor mounted to the ignition switch assembly is located inside the upper right side of the steering column. The passlock sensor contains two hall effect sensors: a tamper hall effect sensor and a security hall effect sensor. The tamper hall effect sensor is mounted on top of the security hall effect sensor. Should someone attempt to defeat the system by use of magnetic experimentation, the tamper hall effect sensor will activate first.
The BCM has the passlock controller integrated into it which controls the majority of the security systems logic. The BCM reads the data from the passlock sensor continuously. If the data is correct and has been received by the BCM within a specified time, the BCM will send a coded password to the PCM. The PCM will then allow the fuel injectors to operate.
The coded password for the security system is sent from the body control module to the PCM via the class 2 data link. If the password is correct and received within the specified time, the PCM will allow the fuel injectors to operate.
The IPC contains the security telltale. The security telltale has three modes of operation, OFF, FLASHING, and ON.
SECURITY TELLTALE will be off if:
?€¢
Ignition is in the OFF position


?€¢
Ignition is in the RUN, START, or ACC position and security system diagnostics have all PASSED

SECURITY TELLTALE will be on if:
?€¢
The BCM is performing a bulb check at vehicle start


?€¢
Security system diagnostics have not yet completed at vehicle start


?€¢
A security system diagnostic trouble code (DTC) is set in the BCM or PCM

SECURITY TELLTALE will be flashing if:
?€¢
The tamper hall effect sensor has been triggered


?€¢
Incorrect passlock sensor data to BCM for more than 5 seconds during vehicle start


?€¢
No passlock sensor data to the BCM for more than 5 seconds during vehicle start


?€¢
Incorrect password from the BCM to the PCM after 5 seconds during vehicle start

No ,the box is probably not bad , but you need to have it programmed . The dealer is the only one that can do that ? The keys don't matter .

Sorry but you can't just replace parts , you need to know how the system works . You need to take this to a ASE certified repair facility that knows how it works .

How to determine the resistance needs to bypass the TDM and passlock on my 04 Chevy Impala


You can't
The Passlock?"¢ sensor contains 2 hall effect sensors. The tamper hall effect sensor is on the top. The security hall effect sensor is under the tamper hall effect sensor. Both of the hall effect sensors monitor the magnet of the lock cylinder through an opening. The tamper hall effect sensor is physically placed on top of the security hall effect sensor. This arrangement enables the tamper hall effect sensor to engage first if an intruder attempts to bypass the Passlock?"¢ sensor by placing a large magnet around that area of the steering column. There is a tamper resistor inside the Passlock?"¢ sensor in order to help prevent tamper to the system. Passlock?"¢ equipped vehicles have a selection of 10 different security resistors ranging from 0.5K ohms up to 13.6K ohms. Installing one of the security resistors inside the Passlock?"¢ sensor will generate a unique Passlock?"¢ code. All 10 combinations of the Passlock?"¢ sensor have the same part number.
Ignition lock cylinder has a connector with three wires marked A-B-C , A is a yellow wire - signal to the BCM .

What happens with Bad Hall sensor?


the "Hall" sensor is a magnetically operated switch (actually a coil of wire) that senses the magnetic field pulses from the motor as it rotates and sends these signals to the C.C.U. control unit on the machine,if this switch goes open it cannot read these signals so most of the time it will show "LR" code which means" Locked Rotor "the actual terminology is "Hall-Effect" Sensor

Hello, I am having a problem with an LG WM2277HB Washer, I have received the LE error. I have tried to unplug, drain water, and disconnect water all for 2 hours. On this forum I noticed a few techs also...


Hi from retired Englishman in SW France,

'LE' stands for Lock Error. There is likely to be a problem, particularly during spin, with either the door solenoid/lock or the 'door closed' sensor (hall effect- magnetic field 'over' the 'hall-effect' sensor) requiring a service engineer's attention I suggest ;-0(

If this has assisted and/or clarified the situation for you please consider a 4 thumbs up on our rating.
Thanks and good luck!

The washer does not run through the wash cycle. The door locks but nothing further happens. There is an "LE" error message but I do not have a manual that explains what that means. Please help.


The LE error message means locked motor error and it is almost always accounted for an out-of-order Hall Effect Sensor. Other causes includes defective Main Board and broken wiring harness.

To check the Hall Effect Sensor:
  1. Unplug the machine.
  2. Remove the top plate assembly by unscrewing the two screws on the back of the top plate.
  3. Look for the Main Board assembly on the rear left side of the machine.
  4. Remove the power connector and sensor switch assembly.
  5. Remove the Main Board assembly protection cover by releasing the latches along its sides.
  6. Look for the 4-pin white connector with white, gray , red, and blue wires. It is the wiring harness going to the Hall Effect Sensor. Disconnect it from the board.
  7. Using a multimeter, check the resistance between the white and blue wires and between the white and red wires. Resistance should read about 10k ohms.
  8. If either resistance reads open, check for a broken wiring harness and repair or replace as necessary. Otherwise, the Hall Effect Sensor is defective and must be replaced.
  9. If the tests above show that the Hall Effect Sensor seemed to be good, you have to check if the Main Board delivers 10 to 15 Vdc supply to it.
  10. Reconnect the machine to the power outlet.
  11. Press POWER but DO NOT PRESS START.
  12. Set the multimeter to DC volt and measure the voltage between white and gray wire terminals on the Main Board. Voltage should be 10 to 15 Vdc. Otherwise, the Main Board is defective and must be replaced.
  13. Connect the red test lead to the red wire and the black test lead to the gray wire.
  14. Turn the motor rotor slowly by hand.
  15. You should measure a pulsating 10 Vdc if the Hall Effect Sensor is okay.
  16. Repeat the step with the red test lead connected to the blue wire.
  17. If you measure a 10 Vdc but not pulsating, the Hall Effect Sensor is defective and must be replaced.
Feel free to inform me if the Hall Effect Sensor or the Main Board needs to be replaced and if you want to replace it yourself.
