Whirlpool 321/3, slow turn during spin cycle

[menditmike]

Hi all
I have a similar problem with Whirlpool 321/3, slow turn during spin cycle the motor is Ceset MCA 38/64-148WHE3 1.7A 380W. Arcing can be seen under the machine and the commutator was black. I turned it upside down to get at the brushes and found 1 was sticking in its holder I freed this by scraping the carbon (10mm carbon left when fully extended). The carbon on both is split down the centre and may be wedging, is the split a fault or is each brush 2 parts? I removed the hose connected to the drum but no ball just view to what looks like the heater element (am I missing something?).
1 Do I need new brushes with 10mm left (should they be split)?
2 Do I need a ball for the hose?
I read elsewhere about a dry joint problem on a motor control PCB, I would like to check this can someone tell me exactly how I get to it?

Thanks menditmike

Sorry to cause you offence, this is my first time and I don't have a clue what I am doing.
Some patience and guidance would be appreciated.
Thanks for the warm welcome.

The carbons are broken. You need to replace them.

Thanks sleepyhead.
After modification & reassembly it is working again but in light of your information I expect it to fail sooner or later. No doubt at the most inconvenient time acompineid by a flood or plague of locusts.
I will order some off ebay perhaps.
Thanks again
