Dishwasher query

pollypenny

Could someone please explain to me how and why my Bosch on eco setting and taking 3+1/2 hours is meant to be green?

It's at 50 degrees, but I would have thought that the length of time cancels any saving. The next setting, 65, takes 2+/12 hours.

The dishes gleam, but it's just the time factor. I was desperate for a soak in the bath yes, but thought it would never fill with the dishwasher running too.

Your manual should say how many units of electricity each programme takes. Heating the water takes more energy than running the pump for extra time I s'pose.

Can you not put the D/W on pause while you take a bath? I have to do that with the W/M here or risk getting scalded in the shower

It won't heat the cabinet (thereby using energy) for the drying cycle at the end. It uses the residual heat to dry the dishes so it takes longer.

It takes four things to clean stuff: agitation, temperature, time, detergent. Temperature is the expensive one so they reduce that & increase the time to get the same wash results. You can't increase the agitation (power of the sprays) or the detergent strength as you'll damage stuff.

Dishwashers don't use much water, it will hardly affect your bath.

They get the energy down by using less water on the eco cycles.

Same with washing machines on those the regulations allow them to use lower temp than stated not checked dishwashers.

Some have multiple pressures for the sprays arms.

My new one has a 3rd high pressure arm for the bottom rack.

The best machines use 6ltr for a wash decent ones under 11ltr.

And they use cold water input so don't touch the hot water supply.

Heating up water uses a lot of energy, pumping it around and spraying the dishes uses very little, so the eco cycles use lower temperatures and soaks things for much longer, like you in your bath, they let the soaking do the work, saving energy overall.

But I don't get why you are waiting on the dishwasher before having your bath? There's no need to.

Brilliant answers. Thank you, all.

The soaking and residual heat are clearly the key then.

I can't see any reference to wattage in the manual, so I've been wondering about it. I was a,so wary about running a bath when the dishwasher was running. It seems as I once it's going, and soaking, I can soak too.

The volume of cold water used by a dish washer will not reduce the volume available to use for bathing.

Thinking more of flow. As we have a combi boiler, I was thinking more of trying to draw hot water in two places at the same time

In fact, when two taps are running the flow is reduced.

Anyway my question has been very well answered above.

We use the vario speed button on our Bosch, which brings the time down from over 3 hours to 1 hour 37 mins. Which for some unknown reason is exactly the same time as the setting we use on our Bosch washing machine.

Variospeed plus works well for me too.
