Fill the five-gallon can from the creek. Pour three gallons into the three-gallon can, leaving two gallons in the five-gallon can. Empty the three-gallon can, then pour the two gallons from the five-gallon can into the three-gallon can. Fill the five-gallon can from the creek. You now have two gallons in the three-gallon can and five gallons in the five-gallon can for a total of seven gallons.

Remove the pilot injector from old unit and fit into new unit

It took me ages to get his to work - seems that on the THD2023GB (Black) Filtrino, you push and hold the temp. set button for 10 seconds to get he descale programme running.

We had the same problem. Mechanic had to come and replace the lock. Took him less then three minutes to open the door, remove the old lock and put a new one in.

Having the same problem with mine. Looking for a replacement generator. Seems that if your water pressure or flow is not adaquate your will have this problem. Get worse over time. I took mine apart and it got better then started doing the same thing again. I turn on several faucets to overcome problem. Still it not good. The 1600H does not appear in the Bosch website parts list models. They do say that a third party does the fulfillment in the notes at bottom on other units...maybe call them

I had that happened twice to me by now.
Turns out to be dirty burner unit.

I got a "removal cleaning reinstallation" bulletin for the model 74 that I went by.
I basically took the burner unit apart cleaned it out (compressed air) and put it together again.
That did it.

you will always have this problem in city type of appltcations.there is too much of a flow differation.

I have a Lowe's Whirlpool water heater. I've experienced the same problems as I've seen described here. My pilot light started going out several times a day. It was not such a big deal, the tank is well insulated so the water would stay warm - I'd just re-light the pilot before going to bed and before going to work. That worked well for about three days, but the problem got progressively worse until it just would not light at all. I replaced the thermocouple with a Honeywell universal thermocouple that I got at Home Depot - that did not solve the problem. I'm very handy, so I decided instead of going through warranty service and having to wait three or four days for replacement parts, I'd buy a new gas valve at Lowes and try that. It cost $54.00 and it worked. By the way, I put the original thermocouple back in and the pilot light stays lit - it was definitely the gas valve and not the thermocouple in my case. It was a real pain to do since I had to drain the tank, but it only took about three hours total. From what I've read, these things last anywhere between six months and two years. That's ridiculous, but at least I have hot water now. If you are reading this because you are considering purchasing a Lowes hot water heater, DON'T!!! I started my search for a replacement gas valve at Home Depot, but they don't stock them. Lowes had 8 on the shelf. That tells you something right there - the water heaters Home Depot stocks don't need to have the gas valves replaced before the tank wears out - there's no demand for the valves so Home Depot doesn't stock them. Lowes probably sells 8 of them a week - all the boxes were shiny and new, not dirty and dusty like some items get when they sit around in home improvement stores.
