Trouble shooting codes F 78 model mhwe400ww01

Many digitally controlled washers have a trouble code list located in the back of the owners manual. These are frequently limited information such as , door is open, load off balance, etc but they do tell you how to rest a simple problem. If it's more complicated then write down your make and model number and go to repairclinic.com for model specific information in the self help trouble shooting section.

Do a cold start....unplug for 5 min.....this should reset the error code...if it returns trouble shoot that area.......

It's very difficult to advise on a noisy washing machine because you can't describe noises accurately enough. People often describe the same noises quite differently.

Generally though, if a washing machine is rumbling, and noisy on spin, the main suspect is the drum bearings. Drum bearing failure is common on washing machines due to water getting into them if the drum bearing seal fails. To check for drum bearing failure you can take the belt off and spin the drum by hand. If the drum rumbles when spun then the bearings have probably gone.

Another drum bearing failure symptom is excessive up and down play in the drum which can be checked for by lifting the drum up and down from the drum lip behind the door seal. A further symptom of drum bearing failure is a brown rust patch underneath the washing machine and down the back of the outer drum, underneath the drum pulley (where the belt goes) There are usually two small holes at the back of the drum bearings where water that has got past the drum bearing seal trickles out, and it's usually stained with grease and rust.

Other causes of a noisy washing machine are coins and other obstructions inside the water pump. This will cause noise when the washing machine is emptying the water. Coins or other obstructions can get trapped between the outer tub and the inner drum. This would produce a lot of noise on spin as they coins get tossed around inside. Usually, spinning the drum by hand will not reproduce the noise in the case of coins as the coins drop to the bottom of the tub when the washing machine isn't spinning.

A light scraping noise when the drum is turned by hand is usually a bra wire trapped between the tub and drum.

A high pitched squealing or harsh noise can be motor bearing wear. This can also be checked for by taking the belt off and running the motor alone.

A knocking noise can be a loose tub weight. This would be worse with heavy loads and would not be present on spin with no washing in. This is because the knocking noise is caused when the tub (or outer drum) shakes about on spin. Without washing inside the drum the tub doesn't move. Another symptom of a loose tub weight is grey concrete dust under the washing machine.

It's very tempting to ignore noises while the washing machine is still otherwise working. Some noises can be ignored as they will not develop into serious faults. Other noises, if left, will cause extensive damage and can end up costing considerably more than if tackled early or these days writing the washing machine off. Of course the problem is that you can't tell which of the categories a noise falls into - so ignore them at your own risk.

You are right!

Bearings have to be replaced. Replace with the same type and design. All the bearings connected to the washer center shaft has to be replaced at the same time with new set.

Replace the water seals also connected to this. Check the shaft where the bearing sits, for any abrasions or metal damage.

Check the bearing housing also. While carrying out these repairs check the drive belt also. If needed replace it.

If you are happy with the machine outer body and other aspects repair it and re-use it.

You will need to remove the back cover plate of the machine and locate the large pulley at the end of the drum. Remove the belt, then the pulley and you should see a bearing housing. Some models require a bearing and housing replacement, while others can simply be repaired with a bearing replacement alone.

Or you can try ordering direct from LG. If you are as handy with tools as you say, this should be a fairly easy job.

I am not a repair professional. I am just a 78 year old
man who has been making his own repairs for about
50 years. Therefore the washer ID doesn't mean
much to me. It's been about 55 years since I had
experience with front load washers. However I can
suggest you go to www.applianceaid.com where
they have very good trouble shooting and repair
information on front loaders. I think you'll find what
you need there. Good luck with it.
