Disassembling a Hansa dishwasher

No one in their right mind would climb inside a dishwasher just to look at the internal structure of the equipment, because this could accidentally damage the equipment. It’s a completely different matter if the machine is already damaged and needs repairs. Therefore, usually, if you need to disassemble a Hansa dishwasher, it is only in order to carry out a thorough diagnosis and restore its functionality. We’ll tell you in detail about this process so that you don’t break anything during disassembly, and then calmly put everything together.

First, let's prepare the machine

First of all, before disassembling, it is important to understand that the most basic components of the “home assistant” are located at the very bottom of the device. From the outside it may seem that there is nothing simpler than simply turning the washing machine upside down, removing the bottom tray and thus getting to all the necessary elements. However, in reality everything is much more complicated, so you definitely shouldn’t rush into analysis.

First, let's move on to preparation, because preliminary preparations are no less important than disassembling the dishwasher itself. Without equipping yourself with a spacious workplace in advance, you shouldn’t even take on the job. Therefore, first you need to prepare everything you need in a home workshop, and if there is none in the house, then we will improvise.

• Remove the Hansa dishwasher from the niche of the kitchen cabinet in the case of built-in appliances, or pull the appliance out of its place if you have a free-standing machine.
• Disconnect the equipment from all communications by disconnecting the power cord, inlet hose and sewer hose.
• Cover the floors of the makeshift workshop with cellophane, rags or any other soft material that will protect both the floors and the PMM itself from damage.

It is most convenient to disassemble household appliances in the bathroom, because in this way there is nothing wrong with a small amount of moisture getting on the floor.

So in just three steps you can prepare the unit for further procedures with your own hands. All that remains is to prepare the tools for disassembly. Basically, this can be done almost without additional equipment, but a minimum set is still necessary.

• Minus and Phillips screwdrivers.
• Pliers.
• Awl.

This applies exclusively to disassembling the dishwasher. For subsequent repairs, you may need a number of special tools, such as a multimeter, soldering iron, adjustable wrench and many others.

Description of the work progress

The tools are prepared, the workplace is cleaned and equipped, it’s time to start disassembling. The main thing is that you don’t have to worry if you don’t have the proper experience or special education, because everything can be done strictly according to our detailed instructions.

• We use a screwdriver and remove the bottom panel of the machine.
• Open the washing chamber door wide, and then unscrew the fasteners located on the sides.
• Now you need to close the door, firmly grasp its front panel with your fingers, and then, pressing down, remove it.
• We open the door again, now in order to remove the screws from its upper end. At the same stage, you can remove the electronic unit of the PMM control panel.
• The fifth step is to remove the metal plate located strictly under the dishwasher door.
• We remove all the soundproofing material placed under the door, and then unscrew all the fasteners that connect the base to the body of the “home assistant”.
• Carefully remove all dish baskets from the washing chamber.
• Disconnect the sprinkler.
• We find the garbage filter at the bottom and, rotating it counterclockwise, pull it out.
• We also remove the fine filter, which looks like a flat metal mesh.
• At this stage you can see the 4 screws securing the base of the lower sprinkler. They also need to be removed.

At the last stages of disassembly, you should be prepared for the fact that the remaining liquid used in the last working cycles may leak out of the PMM pan - there is nothing wrong with this, but also because of this, it is necessary to cover the work area with cellophane or an unnecessary blanket in advance.

• We remove the heat-insulating material along with the side walls of the machine.
• Only now can the device be turned upside down in order to remove the filler pipe located on the side between the tray and the body of the dishwasher.
• Disconnect the wires in advance so as not to break them when you pull out the pan.

It’s better to first take a photo of the wiring so that you have an example of the correct connection at hand.

• Do not remove the pan too far, but pay attention to its center - there is a plastic housing of the circulation pump, on the side of which the pump will be installed. You need to remove the pump by first disconnecting the power cord and turning the pump counterclockwise to remove the pump.
• The final step is to dismantle the circulation pump itself, for which you only need to loosen the rubber fasteners at the bottom of the part, and then remove the drain hose from the pump body.After this, you can disconnect the circulation pump itself.

This is how you can completely disassemble a Hansa dishwasher with your own hands in 16 steps. As you can see, this is far from the most complicated process, which is much simpler than any repair, however, in a situation where the damaged part cannot be repaired, but can only be replaced, you will cope with this task perfectly, because now you know how to independently get to any PMM unit. The main thing is to strictly follow the instructions, and after disassembling, be sure to reassemble the machine strictly in the reverse order, not forgetting the smallest details.
