How to clean the inside of a washing machine and keep it that way

Another thing is the disc appears white here but the pic he posted later is grey. Could just be the lighting.

Like I said, it's the scaling that makes it look grey. And the white cracks are not cracks but the original white plastic under the grey scaling.

It makes ZERO sense to use a different plastic for the impeller and that disc which for all purposes looks identical to me.

There are aftermarket manufacturers of the impellers. Maybe samsung sourced from them? That could be a case.

Or maybe impeller doesn't get any scaling as it rotates at a high speed. The friction between water and impeller descales it.

Maybe it's designed not to be kept for long hours.

Why don't you run it a second time and tell us what happens? same procedure

Like I said, it's the scaling that makes it look grey. And the white cracks are not cracks but the original white plastic under the grey scaling.

I think it's just wear and tear. The white cracks are only seen on the raised parts which means they got abraded.

But the lower areas of that disc show no damage at all. If it was ABS then the whole disc would have shown damage and not just the raised parts.

I doubt the citric acid in that descaler has done any damage here at all. Not after just one application.

I used only one packet for each cycle.
my machine needed 4 cycles to remove every bit of scales/gunk etc.

If your machine has not been cleaned for many years or scale buildup is heavy, you can use 2 packets per cycle.

Use with warm water, it increases the efficiency.

Since you have used a similar descaler that too four times in a row can you examine the disc around your impeller and see if there is any damage like in post #127?

Mention also how old your machine is, its brand and model#

There is no damages in my machine after using the descaler.
Mine is LG 6.5 kg top load machine. Nearly 8 years old. Still going strong.

No service or repair work done so far.

In theory this is possible.

Let's settle this once and for all and the way to do it is simple.

All @6pack has to do is get a medium size screwdriver and then tap the impeller with the handle. Note the sound it makes. Then do the same with that disc and see if the pitch is the same or higher.

How about it @6pack? simple non-destructive method to tell if the plastic used is different or not?

Won't using citric acid damage the rubber gasket?

Ah, so when you can pay Rs.700 and get six times as much they will only sell you 250gm of this which you are supposed to use in one go. Am I right?

Why don't I see similar warnings from other manufacturers or is this only a Bosch problem? Others don't have a product to sell.

Same reason IFB recommends liquids for their machines and then you realise they don't sell powder detergent only liquid detergent.

With your 600ppm water, you need to descale once a month. No way is their descaler going to be affordable. People end up running it once a year. So scale builds up, it turns into a cement and that can be hard to remove later, at least not without using larger amounts of descaler per session than normal.

The magic number is 00311921, plug that into website of the company they outsourced this from and see attached for what the ingredients are. Having seen other descalers ingredients you can presume Bosch's own descaler is 90% citric acid with the remainder maleic and a pinch of the last one.

Seven years in my gasket looks brand new and there are no leaks in the machine. I don't know if that would have been the case if I had used vinegar instead of citric acid.

Something else citric acid is suitable for. Cleaning Toilet commodes. Western type. Put 50gms in stir the water so it dissolves and leave for a couple of hours. Brush a little after. Cleans well

In fact, pay attention to the rate at which scale builds up in the sinks and around the bathroom and that will give you an indication of what is going on inside your machine.

So how do you manage to use citric acid to clean your machine internals? Do you directly add it into the detergent dispenser, or mix it in hot water and pour it inside the drum, as mentioned by LG?

Just put two scoops of the powder in the drawer. Run tub clean. It dissolves very easily. This way it runs into the machine and cleans out the drawer and pipes.

I'd add half a kilo of some mops as well to swirl the water around the tub.

They say not to put any fabric because during a tub clean cycle, the imbalance sensor is disabled so if the machine goes out of balance it can cause a problem.

Half a kilo or even a kilo isn't enough to send the machine out of balance. More might.

You mean the big scoop which we get with 2kg powder detergent? Won't that be a bit too muc? That too 2x. I am assuming the total quantity would be 120gms.

That's the scoop yes. It isn't much when the water used is 15L so the concentration is under 1%. I'd double it for a top loader full of water.

100gm is standard in the descaler packets sold. It seems like more because you paid for that much but now you can use more for less.

Btw can you post the hardness test of your borewell water? This time of the year I expect its at the hardest
