PMM Bosch's heating element burned out. We began our search for something. A circulation pump is attached to the heating element. We discovered this vendor in 2022 at the lowest price after watching the pricing trends. We set up a split and purchased it. In 30 minutes, a new husband was found. Even though many experts claimed it wouldn't, everything works. However, my husband (we once had our own home appliance repair business) eventually cracked the code that the pumps are interchangeable. He burned out after exactly six months of employment.
