How to seal the tank of an Indesit washing machine?

In some cases, when repairing a washing machine, the plastic tank must be cut to repair components or replace a bearing. What should be done in this case, and most importantly, how to glue the tank of an Indesit washing machine? After gluing, the tank should function fully and become a waterproof monolith. To achieve this, you need not only the right sealant but also know how to reliably bond surfaces. In this article, we'll explore the intricacies of gluing a plastic tank.

The best compounds for gluing a tank

When choosing a silicone sealant, keep in mind that the unit will be exposed to harsh conditions. This includes not only sudden temperature changes and exposure to detergents, but also vibration during certain washing cycles. A wide selection of adhesives and sealants suitable for these requirements is available in stores.

Permatex 81730 is a specialized sealant designed for bonding car headlights and glass. For this reason, its properties were designed for use in aggressive environments. In this case, this silicone sealant is suitable for sealing the plastic tub of a washing machine. A 42-gram tube costs three dollars, but keep in mind that the entire tube will be used for bonding. We recommend taking an extra tube so you don't have to go to the store if you run out.

Kraftool. This silicone sealant is distinguished by its high-temperature properties (withstands temperatures up to 250 degrees Celsius) and its ability to withstand vibration. It was originally developed for repairing pumps, motors, and other components. After applying the adhesive, the plastic tank performs its intended function perfectly. It eliminates the need for bolts to create a strong connection. A tube costs four dollars, but in typical cases, it's enough to bond three or four tanks. Professionals often use this adhesive to achieve a strong connection.

It's not a silicone sealant, but a polyurethane adhesive. It can be used to bond the halves of a tank or drum together almost permanently. After two to three hours, the joint hardens completely, making it impossible to separate the halves. The adhesive costs $11-$12 per 310 ml can.

When using it, remember that the next time you need to repair it, you won't be able to disassemble the connection; you'll have to cut the tank apart.

ABRO 11AB-R. An excellent sealant suitable for bonding individual parts operating in harsh conditions. It withstands high temperatures and is resistant to chemical and mechanical stress. After use, the joint is completely sealed. The cost is approximately six dollars for an 85-gram tube.

How to ensure a strong connection?

By manufacturing non-detachable components, Indesit washing machine manufacturers create a significant burden for technicians. If a component breaks or a bearing needs replacing, it's recommended to replace the entire unit. This option is suitable for European countries, but in our country, technicians will attempt to disassemble and repair even non-detachable components. In any case, such a repair will be less expensive than a complete replacement.

In some cases, repairs require cutting the tank apart, and only then can the necessary component be accessed. After the repair, the tank's seal must be restored. For bonding plastic, sealant is the first choice. However, it isn't always up to the task. For this reason, technicians are forced to join the halves with bolts and nuts, and seal the gap with sealant.

When gluing, it's not recommended to skimp on adhesive and use cheap alternatives. Repeated disassembly and leak repair may prove more expensive than using a high-quality adhesive.

How should it be glued?

To properly glue the cut tank back together, certain steps should be taken to ensure precise gluing. Before sawing, we recommend making several holes along the seam with a small drill. After the repair is completed and the halves are joined, the holes made will help to properly connect the cut parts.

Regardless of the adhesive used for the repair, we recommend joining the halves with bolts and nuts. When using additional fasteners, there's no need to wait for the sealant to dry. After complete assembly, wait a few hours for the sealant to dry, then turn on the washing machine and start a wash cycle.

After this type of repair, it's impossible to give a full guarantee that a glued tank will be repaired and leak-free. If you follow the recommendations provided and use high-quality materials, the risk of leakage is minimized.
