Hi Guys and Gals

I got my new machine yesterday (JL1202) after reading good things about it on this site. So far I'm impressed.

Anyway, I have a couple of questions about the machine and I wonder if anyone can answer them?

Before the first wash the instruction manual says to pour 2l of water in to the detergent draw to 'activate the eco valve'. What is this so called 'eco valve'?

Those familiar with the machine will know you have various wash options including economy 60, 40 etc. If I select economy 60 the wash time is longer than that of a normal 60 wash. According to the instruction manual the economy 60 wash takes longer than the normal 60 wash but uses less electricity. How is this possible?

Nothing of major importance but I'm just curious :huh:

All the best.

The eco valve will be inside the sump hose, which leads from the bottom of the tub to the water pump. Many years ago, it was realised that when water first entered a washing machine (taking some of the washing machine detergent with it) some of it went straight into the sump hose and was effectively trapped there - wasted. The solution was to energize the cold water valve for several seconds first in order to fill the sump hose up before flushing the detergent into the machine. Most washing machines now have a plastic ball or valve at the top of the sump hose that allows water into the sump hose, but when the sump hose has filled, this valve floats up and seals off the tub. Once done it's safe to flush the detergent into the washing machine as none can go into the sump hose. The "activation" procedure will be to just ensure there is water inside the sump hose prior to the very first wash.

Washing at lower temperatures may require longer to achieve the same results. It's trading saving energy used by heating water - for more time washing or soaking, which allows the detergent to work more effectively, especially biological detergent.

It will be to do with using less electricity but more time either washing or soaking. It's trading energy used by heating water for more time washing or soaking, which allows the detergent to work more effectively, especially biological detergent.

Thanks very much for the reply. Very informative and detailed. I will be able to sleep easy tonight :lol:

Thanks again
