After few weeks of tinkering and watching videos, finally disassembled hot-end.

Please advise anyway to buy just the 2 nozzles found badly clogged in photos sent.

Buying complete hot-end is easy way out for 1-for-1 swap.
Thermistor, 2 fans and heating element with thick red wires still okay.

Also confirm any ball-bearing(s) inside aluminum heater block after 2 pairs of grub screws removed
(blue arrow with blue text). If none, advisable to drill straights through?

Thanks a lot

Actual photo here amended. Thanks.

Hi,it is with ball, no need to drill through.

Possible to get diagram (photo showing A10 below) of A10M hot-end that may show
ball-bearing inside heater block acting as check valve. Thanks.

P.S. -- Best only front view of A10M diagram.

Ball bearing, 1 or 2, apparently stuck in solid gunk.

Can Acetone dissolve this gunk to free up the ball check-valve
to function properly?
Cannot drill out unless diamond-tipped drill is used.

Poor Technical Support still cannot answer since 18 May, 8 days ago.

Answer eventually in few days/weeks to come ---- Buy new spare?

Hi，it is not recommended that you remove the check valve as it will block the hotend.
