There are several reasons why a fridge may be losing water, some of the most common ones include:
Clogged drain: If the fridge's drain gets clogged with food, ice, or other objects, the water that condenses inside the fridge won't be able to escape and will accumulate at the bottom of it.
Water filter: If your fridge has a water dispenser, it's possible that the filter is clogged or needs to be replaced. This can cause water to leak into the fridge instead of coming out of the dispenser.
Water system leaks: If the fridge is connected to an external water source, such as a pipe, there may be a leak in the water system causing the water accumulation.
Cooling system issues: If the fridge's cooling system is not working properly, this can cause water to accumulate inside it.
It's important to investigate the underlying cause of the water loss in the fridge in order to properly solve the problem. If the problem is not solved, there may be damage to the fridge or even to the floor where the fridge is located. If you're not sure how to solve the problem, it's recommended to consult a technician specialized in appliance repair.
