What 164 (SmartDrive) Means
Fault 164 applies to SmartDrive phases 4 and 5. The module has been trying to brake for twenty seconds, and F&P notes that all spin loads should come to rest within ten - so something has gone wrong during braking that is preventing the bowl stopping in time. The primary source named is the wiring.
Common Causes of 164 (SmartDrive)
- A motor harness problem interrupting the braking circuit
- A connector not correctly applied at the motor or module
- A rotor position sensor problem on Phase 5 machines
🔧 One Safe Check You Can Try
Unplug the machine and stop using it. A drum that takes twice as long as it should to stop is a safety matter rather than a performance one, and there is no owner-level check that changes that.
⚠ Why You Shouldn't Go Further Than That
- Leave the machine unplugged and unused until it is inspected, because a drum that will not stop within its designed time is exactly what the lid lock timing is based on.
- Measuring motor harness resistance between phases is the documented check, and it has to be done with the machine dead and connectors parted.
- F&P names different parts for Phase 4 and Phase 5, so identifying the phase is part of the diagnosis rather than an afterthought.
- Running further cycles to see whether it improves puts the same braking load through a circuit that has already failed to do its job.
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.
