Review the first repair

Ask for the test that identified the failed element, replacement part specification, and post-repair checks. Was useful hot-water delivery measured, or was the heater simply turned back on?

Provide the model, repair date, invoice, and whether performance ever improved. Note all affected fixtures, overlapping use, and how quickly hot water cools.

Do not open covers, perform live electrical tests, or reset controls yourself.

Recheck the cause

A. O. Smith's electric hot-water bulletin distinguishes delivery checks from investigation of thermostats, an element, and the inlet tube. Those possibilities need actual findings, not repeated parts guesses. A. O. Smith electric hot-water guidance.

Ask qualified personnel to check the supply, installed element rating, controls, relevant wiring, and actual heating performance under the model's procedure. Request the measurements that support each conclusion.

The original part may have been faulty while another problem also remains. The original diagnosis may also need reconsideration. The records should establish which explanation fits.

Separate tank heating from fixture delivery

Ask whether the heater produces suitable hot water and whether it reaches the affected fixtures. If a fixture, mixing arrangement, or household plumbing condition is involved, have an appropriate plumbing professional assess that work.

Do not increase temperature to conceal an unresolved delivery problem. Request scald-safe operating guidance from the responsible provider.

Decide on the next work

Clarify whether the follow-up is part of the prior repair commitment, covered parts work, or a new paid diagnosis. Get the scope and charges before authorizing it.

A replacement recommendation needs the equipment-condition evidence and comparison with a supported repair. Another element needs its own failure finding.

Your next step is to return the unchanged symptom and first repair record to the provider. Request a written diagnosis and a hot-water result check that demonstrates whether the correction addressed your concern.
