When you buy a new washing machine, it's important to look at the leak protection. That's because a water seal on your washing machine protects you from leakage. There are 3 types of leak protection: a bottom leak sensor, overflow sensor, and safety hose. If your washing machine leaks, the machine will automatically shut off the water. This prevents damage to your wood floors. On this page, you can find all washing machines with all 3 types of leak protection. That way, you're protected best.
