If you can't watch the video follow the steps below:

When a customer can't close and latch the door and you see the door latch looking like this you know you'll have to replace the door lock assembly.

Start by removing the spring around the door boot with a pliers or screw driver

Remove the door boot so you can place your hand inside the cabinet to reach the assembly


Unscrew the two screws above and below the door strike. If the assembly is broken you might need to hold it tight to the inside of the cabinet to get the screw out

Reach inside and grab the assembly. Lift UPWARDS first and then pull the whole assembly to the door opening. There is not much slack

There are four plugs to undo. The top plug with black wires

Blue wire in middle is hardest because it is the smallest and has a catch you need to push out of the way in order to get the plug out as it is very easy to pull the wires out of the plug

Pink wire in middle
Big white plug on bottom

Most common areas for these to break

A complete unit

Reattach wires and place back inside cabinet.
This time angle the assembly so the catch inside the cabinet grabs on to the assembly to hold it in place. Remember this is why when you removed the broken assembly you had to lift the assembly UP first

If you can't get the assembly to hook onto the catch just hold it so the door strike is through the cabinet

Screw assembly in

Move door boot back over the edge of the door opening ad place the door spring back around it to hold it in place. VERY IMPORTANT TO REMEMBER

Door lock assembly replaced and ready to wash

Problem with Hard Piped Washers

 

Many laundry equipment installs involve taking the large chassis washers and instead of draining them into a drain trough that is built in the ground or an above ground manufactured drain trough, they are hard piped from the machine drain directly into the drain system. This method is not to code in all areas of the country as some areas do require large chassis washers to drain into a trough. There are advantages to hard piping:
1. saves the cost of digging a trough into concrete or buying a manufactured trough
2. don't have to try and retrofit a drain trough inside a narrow bulkhead
3. you can "hide" all the pipes inside a bulkhead unlike some situations where a drain trough might be in the open
4. no moldy smell of an unclean trough wafting in the store
5. there is nothing to clean out like an in ground or manufactured trough...

-OR IS THERE?

The disadvantages of hard piping are:
1. possibly illegal in your area to hard pipe machines into a drain line as local requirements might state that gravity drained machines have to dump into a "holding container" like a drain trough
2. hard pipes are usually hidden inside the bulkhead and an "out of sight-out of mind" situation develops so the pipes are rarely inspected for leaks or blockages until something breaks
3. all of the debris that gets caught in the pipes and stops the flow of water away from the machine and potentially keeping debris in the drain valve area longer resulting in stuck drain valves
4. debris can also cause the washer to drain slower leading to potential machine errors that could stop the cycle and cause an upset customer  

If you hard pipe your machines you still need to clean them on a regular basis. As you can see in the pictures below there are tons of coins, nails, hair pins, etc. in these pipes and it combines together to form big chunks after a time. How often you have to clean them depends on your usage, however make sure you install clean out plugs and don't glue or "permanently attach" the hard pipes to the washer drains so you can easily detach them and clean out the pipes.
At this store this is only four of the 24 hard pipe connections.
If these had been cleaned more often not only would the owner have not had the service issues and customer issues he had, but all of the money could have been saved because it would have been in usable condition. That is a few hundred bucks from this store easily.

Clean your pipes!
