washer 3 prong to two prong old house 1940


Clothes Washer Label:
"Plug into a grounded 3-prong outlet. Do not use with an adapter. Do not use an extension cord. Do not remove the ground prong."

What to do? Ground 3rd to pipe, to ele box, or what should I do?

tks,
pa

Either plug into a grounded outlet, if possible with out extension cord, rewire circuit and install grounded outlet, or install gfi. If I were you, the safest thing to do would be to rewire the circuit and install a grounded plug

Install a GFCI receptacle and label "No ground" if you cant run grounded wiring.

The ground is there to protect YOU! Not the machine.

If the GFCI senses an unbalance in load, (ie. machine shorts out) it will trip.

I wouldn't "rewire" anything. Just have a new circuit run for the washer.

GFCI would be easy. Is that up to code?

Yes, it is code compliant to replace the ungrounded receptacle with a GFCI labelled "no equipment ground". It is also pretty safe. I would not want a washer connected to an ungrounded circuit without a GFCI.

EDIT: 250.114 does not allow the use of this exception on a washer, because it specifically requires washers to be on grounded circuits. If you already had a GFCI there then it could be arguable since the house is older than 250.114, but if you have to modify the circuit to comply with code then the only legal solution would be to run a grounded circuit.

Article 250.114 requires that the washing machine be used on a grounded circuit. Installing a GFI would enhance safety, but would not meet the code or the instructions included with the washer.
