I have a fairly new (3 months) Edgestar countertop dishwasher. It has started making a very loud grinding- type noise when the spray arm is operating. It also is now leaking slightly from the bottom of the unit. Thank you in advance for any advice.

the arms are only turned by water coming out of them thro angled jets, they are not electrically driven. the noise will be coming from the circulating pump, probably one of the bearings. no cure except to replace

clogged flowplate...... replace flowplate assy, you might try muratic acid first, it will clear alot of the common problems. be careful its poisonous to the max, when you have the flowplate assy off check entire are for foreign objects.

I have a very similar dishwasher, with a very similar problem. I fixed it by removing debris from the water evacuator pump located towards the front of the bottom of the machine (the last motor before the drain hose. In my case, grape stems had clogged it up. Once emptied, it purrs once again. NOTE: don't disassemble the motor, just flush it out, there is an o-ring gasket that is a bear to re-install.

Solution #2 by user dwdamron is accurate. I checked the docking nozzle and sure enough the o-ring was gone. replaced the upper wash supply tube with new o-ring and problem was fixed.

We had same problem machine same age, had a service person in and the found that the motor was dying. LG wouldn't cover saying that it was normal wear and tear. b
