Hope someone can help me. I have the grundfos MQ3-45 pump and I wasn't getting enough water pressure. Went to check the pump which had the below lights and when I tried to reset it the pump never came back on. Could anyone help me locate what the possible fault may be ?

Your water pump is blocked. You will need to either call a repair person or disassemble the top of the pump (inside the dishwasher, bottom) and check the water input duct. It just might be some food, etc.. that is blocking the input. But if you don't see anything then it will be further inside and will need to be removed and cleaned. BIG pain...

Best of luck. BTW, I've had the exact same problem but mine was further inside so I had to remove the whole dang pump, arggggggg.

Definately sounds like a leak in the pipes from the pressure side of the pump onwards, even the smallest leak will cause it to turn on to regain adequate pressure.

you have to know what the code is that your truck putting out your truck has 4 O2 sensors. the trucks computer is smart and the code will tell you witch one is bad but if you replace just one the next one on the same exhaust pipe will probley go bad so its safe to replace all four. the draw back to replaceing all of them is thay cost about 80 bucks for one ACDelco O2 sensor. It has to be done before it will pass Emissions. not a hard part to change about a 7/8 open end wrench will take it off. have fun.

hi, unfortunately this is one of them how longs a piece of string things, you could purchase a code reader reset the error code but, what you have to think of is what caused it to do it in the first place, accelerating to hard should not cause an error ( i do it all the time in my car lol ) but it might be related to the 02 sensor getting to much unburnt fuel passing it which would cause the engine light to come on, though if the car is running as normal i doubt that will be the issue, i would myself on a car like that take it to the main dealer and get them to check it out, as buying an inexpensive code reader might not cut the mustard with this one, and parts being as dear as they are for merc's i would play on the safe side, spend a few bucks to save a load...sorry not much help
