Shut off water and remove hose.

Copy following link to troubleshoot by type of gas control valve, including directions for cleaning air intake screen, and or replacing gas control valve:

7 flashes: Gas control valve might be bad.
4 flashes: FV overheat, clean air intake.
Soot indicates clogged air intake slowed combustion venting possibly causing overheating and lockout. Clean air intake screen located on bottom of unit.

The slime is a function of the water that you are feeding the device. Machine has nada to do with it. Unless you clean up your water supply you will continue to have this problemo.

1) Copy following links:

http://waterheatertimer.org/How-to-repair-Rheem-TRD.html

2) GE is made by Rheem, so air intake screen is located below the combustion burner, as is the TRD (thermal reset device).

3) Modern gas water heaters, the FVIR, or FV system will trip when air intake gets clogged with dust.
This will slow venting of hot combustion gasses, except burner is still burning same amount of fuel. Overheating occurs, and that trips FV system.
Other brands require cleaning air intake screen and possible replacement of gas control valve, or FV sensor, etc. Each model is different.
Rheem_GE overheating will trip TRD, and glass vial breaks, causing air intake to close. Glass vial must be replaced, and possibly the gas control valve replaced.

usually caused by clogging or bad valve. Valve can fail by clogging, torn diaphram, or bad/loose vacuum actuation hose.

Exhaust gas recirculation (EGR) system - insufficient flow detected

Causes: Hose leak/blockage, basic setting not carried out (if applicable), wiring, EGR valve, EGR solenoid, ECM

Your EGR valve should be on top of the engine in the front between the intake manifold and the pulleys. It looks something like this:

First, make sure the vacuum hose is good and run it down to where it connects to the intake manifold to check for any leaks. If that's good and you want to get your hands dirty, take the valve off and see if it's clogged. clean it and see if you can actuate it with vacuum (put a vacuum hose on it, ****, and see if it will open. Also, look to see if there is gunk in the line and intake where it connects. Clean out anything you can with carb cleaner.
If you can get it unclogged and the valve is working, put the valve back on with a new gasket, else buy a new one ($40 at autozone :o( ). If you solve the issue, the engine light should clear after a couple hours of driving. OK?

Check your water pressure. Disconnect the water line at the intake valve. Hold the end of the water line over a bucket and turn on valve. See if any deposits come out and check the water pressure. There is a fine screen at the intake valve which can get clogged if you have crud in your pipes. Get a mirror and flashlight and inspect it.

Check the water intake screen for sediment. Sometimes if sediment partially clogs the screen, the water pressure is lowered significantly enough to cause these conditions.
If you send me the make & model of your DW I'll tell you where the intake screen is. Sometimes its on the bottom which is a pain because you have to pull the DW out of the cabinetry...

If it is not just badly clogged, the intake does not need to be cleaned out. If you want to clean it out then take some brake cleaner and spray it in there and wipe it with a rag. I have never seen someone have to clean the intake due to not being clogged. Just my expierence I would just change the EGR and go from there

Replace or clean your water inlet valve. It appears that the hot water solenoid has either become clogged, or had failed. You can find a replacement at repairclinic.com. Type in your COMPLETE model number in the Search window and there will be two of them located under the "Water Valve/Float" heading. Depending on WHICH type of valve you have, a replacement costs between $28 and $74. Refer to the part illustrations to make sure you are ordering the correct part. If you require assistance in accessing the inlet valve, let me know. I hope this helps you.

PS If you attempt to clean the valve, you will need to turn off the water supply and disconnect the hoses. Check the inlet screens for sediment or debris.
