What F40 / F44 / F72 (110 / Whirlpool-built Oasis) Means
Three distinct Oasis faults sharing one platform: F40 for the inlet water temperature thermistor, which on this generation is built into the inlet valve assembly; F44 for a failed heater relay on the main board; and F72 for a basket that will not re-engage the drive for the spin.
Common Causes of F40 / F44 / F72 (110 / Whirlpool-built Oasis)
- A thermistor failed inside the inlet water valve assembly
- A heater relay failed on the main electronic control board
- Water left in the tub preventing the basket engaging for spin
🔧 One Safe Check You Can Try
If F72 is showing, check first whether the tub actually drained — the documented route begins with running a drain before the basket is blamed.
⚠ Why You Shouldn't Go Further Than That
- The thermistor is part of the valve assembly here, so it is not a small standalone sensor swap.
- The heater relay lives on the main board, which means a relay fault is a board replacement in practice.
- Basket engagement work sits in the drive stack beneath a machine that is heavy and unstable with water in it.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
