Williams says it was left with a "bitter aftertaste" from celebrating its first 2016 podium courtesy of Valtteri Bottas as Felipe Massa was forced out due to an overheating power unit.
Massa, whose weekend was compromised by a DRS-related crash during the first practice session, started from eighth place on the grid and was making steady progress when Williams retired the car.
It ended Massa's achievement of being the only driver to have scored points in every race this season.
"There’s a bitter aftertaste with the fact that we could have had both cars up there," said Williams' Head of Performance Engineering Rob Smedley.
"Felipe would have finished anywhere from fourth to sixth so that’s a lot of points we’ve lost there with the water system issue that caused the temperatures to rise.
"We went through a series of counter measures to try and get round it, but none of them worked.
"We therefore had to take the decision to retire the car because the power unit is right at the start of its life."
Massa naturally expressed his disappointment at his retirement.
"Of course I’m very disappointed not to finish the race because of a mechanical issue that we had," he rued.
"It’s a race where we’re supposed to score good points with both cars, but unfortunately we didn’t with mine."
