Corroded Pump

[Tzmcd9]

Our pump stopped working this past week. It had been shorting out the breaker. The electrician came and discovered the pump was very corroded.
They are replacing it now, it is only 3 years old. Is this normal?
Who should be responsible for the replacement the customer or the pool company?

Welcome to TFP!

No that is not at all normal. What kind of corrosion, and where? Usually that only happens if the motor was somehow getting wet all the time, which shouldn't be happening.

Responsibility is a little bit difficult to determine without getting a better idea of what happened. A plumbing leak spraying the pump would tend to be the installer's problem, but a lawn sprinkler spraying the pump probably isn't their issue. While a defective pump might be the pump manufacture's problem.
