the unloader valve on my ms3125 is leaking water really bad from the sides when i'm using it.
The unloader valve assembly has internal seals that direct high-pressure water. A leak from the body means those seals are worn or damaged, or the valve body i…
-
my megashot won't start at all, not even a sputter. i checked for spark and it's good, gas is fresh.
With good spark and gas, the engine should at least cough. The fact it doesn't points to a lack of fuel actually making it into the cylinder. On these, the mos…
-
oil is leaking from the bottom of the pump on my simpson, looks like it's coming from a little plug. is that bad?
That's the pump oil drain plug. If it's leaking, the seal (usually an O-ring or crush washer) has failed. The pump uses a special non-detergent SAE 30 oil, not…
-
pressure washer surges and pulses really bad, can't hold a steady stream. it's a megashot 3125.
That pulsing is almost always caused by air getting into the water supply side of the pump. The pump is trying to pressurize a mix of air and water. Start at t…
-
just got my ms3125 and it runs for a minute then dies like it's out of gas, but the tank is full.
Yeah, this one's common on new units. The fuel tank cap isn't venting properly, creating a vacuum that starves the engine of fuel after it burns through what's…
-
my simpson megashot starts fine but the pump just hums and won't build any pressure, what gives?
That's the pump motor humming but the piston assembly inside isn't moving. On these, the most common culprit is that the pump was stored with water in it over …

my heater tips over really easy, the feet don't seem stable on my carpet. anyway to make it less wobbly?
The MVH has a relatively high center of gravity and small, hard plastic feet. On thick carpet, these feet can sink in or tilt, making the unit unstable. You ne…
-
the fan speed on low doesn't seem any different than high, it's always blowing really hard.
The MVH is designed as a whole-room circulator first, so even its "low" fan speed is relatively powerful to move air. However, if there's truly no audible or a…
-
is it normal for the plastic casing on my vornado to smell really hot, like a burning plastic smell? it's new.
Yes, this is common for the first few uses of a new MVH (or one that hasn't been used in a long time). It's dust or manufacturing residues on the heating eleme…
