Washing machine tank leaking

A tank leak is one of the most dangerous breakdowns for an automatic machine. In some cases, this failure can be fatal. It is easy to recognize a leak - water will constantly accumulate under the device. However, finding the place of the leak causes great difficulty for users.

The washing machine tank often leaks due to worn bearings or an oil seal. In this case, solving the problem will be quite simple. However, if the matter is damaged to the wall of the plastic container, then the repair will be more serious. So let's take a look at the nuances.

Why is the tank leaking?

Problems with tanks of automatic machines happen more and more often. If the rules for operating and transporting washing equipment are not followed, the likelihood of damage to the tank increases. Modern washing machines are mainly equipped with plastic containers, so you must handle them carefully.

• A leak in the tank can occur for various reasons. Let's analyze the main ones.
• Damaged plastic during transportation of the washing machine. This can happen if the machine is transported without transport bolts. The container will not be fixed so that it will hit other internal parts of the device.
• I wore out bearings and seals. In this case, you can find rusty streaks on the tank's back wall.
• The wall was damaged by a sharp, hard object that fell into the area between the tank and the drum. For example, this happens when a bone from a bra is inside the machine. When the washer runs at high speeds, it can be quite capable of piercing the plastic tank.
• The welding seam between the halves of the CMA tank has leaked. This option is possible if the washer has not been used for a long time (for example, in a warehouse or a store for several years). Another reason is a factory marriage.

What to do when you find a leak? First of all, it is necessary to identify the cause. Suppose the washing machine tank leaks due to broken bearings or an old oil seal. Replacing components will help. When it comes to damaging the walls, you have to be smart.

Washing machine repairers have been fixing cracked plastic tubs for a long time. The defect is sealed, and the machine stops leaking. However, no one guarantees such repairs since the treated area may again begin to let water through.

he ideal solution to the problem is to replace the tank-drum assembly. However, spare parts are quite expensive, and not everyone can afford such a purchase. Therefore, the user must decide whether to solder the crack or purchase new components.

Pull the tank out of the case first.

To understand why the tank of the automatic machine is leaking, the container will have to be removed from the body and inspected. Before starting work, turn off the power to the washer, and turn off the valve responsible for the water supply. Also, prepare the tools required: pliers, slotted and Phillips screwdrivers, a screwdriver, and a set of socket heads. The further algorithm of actions will be as follows:

• Drain the remaining water from the system by unscrewing the garbage filter (it is located in the lower front corner of the CMA),
• Use a screwdriver to remove the bolts holding the top panel of the CMA case,
• Remove the cover, first by moving it back a little and then pulling it up,
• Unscrew all the bolts holding the back wall of the machine,
• Remove the back panel,
• Remove the drive belt from the pulley,
• Inspect the back of the tank of the automatic machine,
• Unhook the wires of the heating element and the temperature sensor from the SMA tank,
• Unscrew the bolts holding the washer motor,
• Pull the heating element out of the socket by loosening its nut,
• Remove the upper counterweights,
• Disconnect the pipes and wires from the water level sensor, carefully remove the pressure switch from the machine,
• Remove the detergent dispenser from the machine, then loosen the hose clamps leading to the powder receiver and remove the dispenser hopper,
• Carefully place the washer on its right side, and see if it has a bottom (if so, remove the pan by unscrewing the bolts holding it),
• Remove the screws on opposite sides of the drain filter,
• Push the snail of the pump, where the garbage filter is placed, inside the CMA body,
• Unhook the chip with wires from the drain pump, remove all tubes from the pump,
• Remove the pump from the CMA housing,
• Unscrew the shock absorbers holding the tank from below,
• Lift the washing machine (do this carefully because the tank-drum assembly will be fixed in the body with only two springs,
• Unscrew the bolts holding the CMA control panel, put the tidy on top without completely disconnecting it,
• Open the drum door, loosen the clamp holding the cuff,
• Pull the clamp out of the body, and fill the cuff inside the drum.

Now nothing will interfere with the excavation of the tank. First, remove the assembly from the shock absorbers and remove it through the top of the housing. Next, you will have to scrutinize the tank.

How to solder a hole?

If it's not the bearings, most likely the tank is leaking along the seam, or cracks have appeared on its walls. You can solder holes in the plastic with a hot air gun and plastic solder. The cost of such repairs will be small. You can buy a pack of bars for 2000-3000. The amount of material that will have to be used depends on the size of the damage on the container.

In addition to the building hair dryer itself, you will need the following:

• Nozzle narrowing the hole of the hair dryer (usually included),
• Welding nozzle that allows you to enter the infusion material (rods),
• Plastic solder in the form of rods.

Mechanic involved in the repair of washing machines are advised to purchase HDPE-plastic welding rods. They are best grasped with the tanks of machine guns. Therefore they are suitable for local repairs of this kind.

The algorithm of actions for sealing a crack in the tank will be as follows:

• Lay the tank on a flat surface,
• Put a narrowing nozzle on the building hair dryer,
• Take a welding nozzle and one rod,
• Place the solder nozzle on the hair dryer, turn on the tool, wait until the air becomes very hot,
• Insert the rod into the nozzle and carefully patch the defect.

When the tank flows along the seam, process it this way along the welding line. This may take about 10 bars. If you consider that there are 40 of them in the package, then you won't have to buy an additional pack.

There is another way to fix a hole in a plastic tank - using a soldering iron. This method is suitable when the crack is small. In general terms, the algorithm of actions will be as follows:

 

Find a piece of plastic that is similar in quality to the material from which the tank is made (the mechanic even saw off a small piece from the same SMA tank in a place where its absence will not affect the operation of the device in any way),

• Put a piece of plastic on the crack and melt it with a soldering iron to patch the defect.
• Having repaired the tank, you can put it in place. Then, the assembly of the washing machine is carried out in reverse order. In the process, checking with the photos taken earlier is recommended to avoid mistakes when connecting wiring and pipes.

When finished with assembly, run a test wash. If the machine stops leaking, then the problem can be considered fixed. However, during further operation, it is necessary to monitor the condition of the home assistant and prevent foreign objects from entering the washing drum.
