What brand. Ih it is a hotpoint. I found this on the net from a washer help site in the uk
Error 30 (on Hotpoint) just means the motor isn't working. Several things, including the power module, can cause this. The most common cause though is worn carbon brushes. There is also a 7.5 amp fuse on or near the power module, which can blow. This fuse is on the motor circuit to protect the circuitry of the power module. If it blows, then the motor won't work and you will get error 30.
If it has blown, it's likely to be caused by the motor. I had one last week where the armature in the motor had shorted to earth which blew the 7.5 Amp fuse.
The E30 code on Hotpoints means the motor isn't working. This can be due to a failed power module, worn motor brushes (very common on heavily used machines) or a failed motor fuse (usually caused by a worn motor armature). Sometimes it's a failed main circuit board, but this would normally be indicated by other erratic behaviour which you have not described, but it's still a possibility but is the least likely cause.
The tricky bit is knowing what has actually failed if you lack the tools and knowledge to make a diagnosis. The fuse is very cheap, but always blows for a reason: fuses don't just wear out. If the brushes are worn out then it's easy and cheap on a Hotpoint to replace worn carbon brushes: see
for an excellent guide regarding this, all credit to the excellent Washer Help website. If the armature (the bit the brushes make contact with) is badly worn then new brushes won't fix the fault and a new motor is the best option. Hotpoint motors are fairly cheap and easy to replace so don't bother with gambling on a worn secondhand motor as it could fail again at any time.
Diagnosing a failed power module involves using a multimeter to test the module outputs. If the module has failed you still need to check the motor as I've known some peculiar armature failures to blow the module as well (even though the 7.5A motor fuse is meant to prevent this!).
Hotpoints certainly aren't the most reliable machines around, but they are relatively cheap to buy and usually cheap to fix. If the motor has worn out then expect the pump motor to fail very soon as well but again it's usually cheap to replace. When the machine is apart, check the drive belt for wear: Unless it's near perfect then replace it as a matter of course.

it's possible that one of the carbon brushes have worn down to the bottom and it is sparking on the motor causing it to trip the fuse. It's just one possibility. Have you checked the carbon brushes are connected properly and that they have not 1) worn down and 2) that the wires are connected to them correctly.
yes easy to change there are 2 of them look for a single wire going to each side of your motor when u find each wire u have found were your carbon brushes are right you will need a pair of bent nose pliers place the ends either side of the plastic casing if the carbon brushes squeeze and pull the first brush should pull out take wire of now the 2 brush you wont be able to see but its directly across from the first 1 do exact same to take that 1 out now before replacing the new brushes there a small slot running down 1 side of the plastic at the end you will see a small metal bar push this up which will release the carbon now you can fit them
