WARNING
Before you do anything to your appliance, make sure you disconnect it from the power supply.
There is a risk of electric shock.
A malfunction of the brewer
When you start your coffee machine, it performs a phase of rinsing and grinding the beans. If, from the beginning, you hear a popping noise, this may indicate a malfunction of the infuser, also known as the brewer or brewing unit. To check this part, disassemble the item to make sure it moves freely. If the plunger is too stiff, apply cooking grease to lubricate it. But if the problem persists, the machine part will have to be replaced.

The guide rail is deformed
The rail/motor assembly is the guide system for the brewing unit in your coffee machine. However, if this rail is deformed, popping noises may occur. In such a situation, it is imperative to replace this complete set. To assess the condition of the rail, remove the brewer and the two Torx/star screws on the back.
Buy a motor for your coffee maker
Abnormal pump noise
If unusual noises occur when dispensing the rinse water, it could signal a problem with the pump. To distinguish this noise from that emanating from the brewer or motor, put your coffee machine in steam or hot water dispensing mode. If the noise persists, it will be necessary to replace the pump. On the other hand, if you notice an obstruction to the flow of water, start by descaling and see if that solves the issue.

The grinder is defective
During grain grinding, if you notice an unusual noise, it could signal a grinder malfunction. To check that it is in good working order, look through the ground coffee hatch or examine the size of the pieces and the fineness of the grind. If the grind is too coarse or the beans are not properly ground, it will be necessary to replace the grinder. You can try to unlock the mechanism by moving the knob while the grinder is running, but if the problem persists, replacing the grinder is unavoidable.
