What you came for
F70 is a report, not a diagnosis: it says the control raised a reading the documentation answers by pointing at a technician instead of naming a part. You can take the power away once to see whether it was a one-off latch, and if it returns the answer is a technician. Work down the ranked causes rather than ordering the part the code names.
What the documentation says about this code
Reference| Code | Documented meaning |
|---|---|
| F70 | The manufacturer publishes this code for this appliance without an owner-level meaning; it is documented for service diagnosis on the model lines that use it. |
Symptoms that travel with this code
- The cycle stops and the display holds the code — It stays until the power is taken away.
- It returns immediately after a power-down — Which is what separates a real fault from a latch.
- NEAR MISS - the code clears and never comes back — Then it was a latch, and there is nothing to repair.
What is usually behind it
- A one-off latch from a supply event — Ranked first because it is the only cause an owner can do anything about, and one power-down settles it.
- A connection inside the machine rather than a failed part — Second: connectors and harnesses account for a large share of codes that look like component failures from the outside.
Check these in this order, and why
- Take the power away once and bring it back — Free, and it is the only owner-side test that tells you anything about this code.
- Resist the urge to keep restarting — Repeated attempts on an unknown fault add wear and tell you nothing new.
What you can do without tools
- Write down the code, the cycle and the point it stopped — A technician arriving with the right part is a technician who was told this.
About 5 min
- Leave the machine unused if it involves heat or water — An unknown fault on a heating or filling appliance is not one to leave running unattended.
- STOP HERE - do not open the machine — Unplug the appliance or switch off its breaker before any panel comes off; a capacitor can hold a charge after the power is off.
The safety line on this appliance
Safety
Safety line for this appliance: unplug it or switch off its breaker before removing any panel, and remember a capacitor can hold a charge after the power is off. Interlocks and switches stay as fitted. A hot plug, a browned outlet or the smell of hot insulation all mean stop and call, whatever the code says.
The point at which you call
The line is straightforward. This is a call rather than a repair: the manufacturer publishes no owner-level meaning for this code, and the diagnosis needs the service documentation for the model line and a meter. Separately and more urgently: call immediately, and leave the appliance switched off at the breaker, if there is a burning smell, visible scorching, or a breaker that will not hold.

How far this page applies
Applies to: the model lines for which the manufacturer publishes this code without an owner-level meaning. Does not apply to: a specific model's wiring, its part numbers, or its service procedures, all of which vary and none of which are invented here. This page is the general reading of one code; where a more specific page exists for your family or model it is linked from the index below and it is the one to read first.
