B3.Date of event: unknown.No information has been provided to date.Investigation summary: the affected device was received for evaluation.Visual inspection showed damage on the pcb pot, a cracked and leaking tank cover, a broken front cover, and the pump was noisy.The tank was then filled with water, the temp check was attached, the line cord was plugged in, and the power turned on.The customer's indicated failure was confirmed as the front cover and tank were cracked/broken and leaked during functional testing.The root caused was determined to be the cracked tank cover.As a result, the tank cover was replaced, along with the pump, pcb, and front cover.After preventative maintenance was performed, the device functioned as expected.A review of the device history record (dhr) shows there were no observations or nonconformities recorded during manufacture to suggest an issue of this nature would occur with this lot of products.
