Your draft is already strong. I’d make a few edits to improve readability, add the actual part numbers, and make it easier for technicians to diagnose.  
**GE Heat Pump Water Heater Completely Dead After Less Than 6 Months - Looking for Diagnostic Help**  
I’m looking for advice from anyone familiar with GE heat pump water heaters, particularly the newer GE Appliances models.  
**Model:** PH65S10BPY01  
**Age:** Less than 6 months old  
**Purchased:** January 2026  
**Failure Date:** May 31, 2026  
The unit has completely stopped producing hot water, and GE has not yet been able to determine a definitive root cause.  
**Current Symptoms**  
No hot water at all.  
Hot and cold water temperatures are essentially identical.  
Water heater is cold to the touch.  
Brass outlet valve is cold to the touch.  
SmartHQ app shows **0 gallons of hot water available**.  
Energy usage in the app appears to have remained at **0 since May 31**, when the failure occurred.  
Unit has been placed in **High Capacity Mode** for testing with no change in operation.  
App unexpectedly switched from Fahrenheit to Celsius.  
Current error codes:  
F16  
F20  
F21  
F50  
**Service History**  
The situation has become increasingly confusing.  
Initially:  
Parts were ordered.  
A technician later determined the wrong parts had been shipped.  
Additional parts were ordered.  
I was later told those parts were backordered and GE was attempting to source them directly from the factory.  
More recently:  
GE reviewed the MAC ID data remotely.  
I was told the sensor appears to be functioning normally.  
I was asked to place the unit in High Capacity Mode and monitor it.  
After more than five hours in High Capacity Mode:  
Still no hot water.  
Unit still cold.  
App still shows 0 gallons available.  
**Parts History**  
This is now the third separate parts order associated with the repair.  
**First Parts Order**  
Two heating elements  
TCO (WS17X22383)  
Ordered June 1  
Arrived late  
**Second Parts Order**  
Ordered after technician visit  
Later reported as unavailable/backordered  
**Third Parts Order**  
Temperature Sensor Assembly (WS17X22385)  
TCO (WS17X22386)  
Promised delivery by noon today  
As of now, tracking does not show the shipment has been picked up  
The latest technician visit resulted in numerous additional parts being ordered.  
Current estimated delivery date for the newest repair attempt is June 29, nearly 30 days after the original failure.  
At this point I have very little confidence that anyone has identified the actual root cause of the failure.  
**Questions**  
For anyone who services these units:  
Do these error codes point to a known failure pattern?  
Is there a component that would explain all of these symptoms simultaneously?  
Has anyone seen a unit show zero energy consumption while still appearing operational in the app?  
Does the addition of the F50 code help narrow the diagnosis?  
Is there anything I can check myself before the next technician visit?  
Has anyone seen a unit require this many parts without a definitive diagnosis?  
Do the part numbers above suggest what GE believes is actually failing?  
I’ve documented the entire process, including 13 customer service contacts totaling more than two hours on the phone, multiple technician visits, and three separate parts orders.  
GE has been actively involved, but before more parts get thrown at this unit I’d love to hear from anyone who has actually repaired one of these systems.  
Any insight would be greatly appreciated.
